0. Intro
The announcement of Uniswap v3 is no doubt one of the most exciting news in the DeFi place recently 🔥🔥🔥
While most have talked about the impact v3 can potentially bring on the market, seldom explain the delicate implementation techniques to realize all those amazing features, such as concentrated liquidity, limit-order-like range orders, etc.
Since I’ve covered Uniswap v1 & v2 (if you happen to know Mandarin, here are v1 & v2), there’s no reason for me to not cover v3 as well ✅
Thus, this article aims to guide readers through Uniswap v3, based on their official whitepaper and examples made on the announcement page. However, one needs not to be an engineer, as not many codes are involved, nor a math major, as the math involved is definitely taught in your high school, to fully understand the following content 😊😊😊
If you really make it through but still don’t get shxt, feedbacks are welcomed! 🙏
There should be another article focusing on the codebase, so stay tuned and let’s get started with some background noise!
1. Uniswap & AMM recap
Before diving in, we have to first recap the uniqueness of Uniswap and compare it to traditional order book exchanges.
Uniswap v1 & v2 are a kind of AMMs (automated market marker) that follow the constant product equation x * y = k, with x & y stand for the amount of two tokens X and Y in a pool and k as a constant.
Comparing to order book exchanges, AMMs, such as the previous versions of Uniswap, offer quite a distinct user experience:
AMMs have pricing functions that offer the price for the two tokens, which make their users always price takers, while users of order book exchanges can be both makers or takers.
Uniswap as well as most AMMs have infinite liquidity¹, while order book exchanges don’t. The liquidity of Uniswap v1 & v2 is provided throughout the price range [0,∞]².
Uniswap as well as most AMMs have price slippage³ and it’s due to the pricing function, while there isn’t always price slippage on order book exchanges as long as an order is fulfilled within one tick.
In an order book, each price (whether in green or red) is a tick. Image source: https://ftx.com/trade/BTC-PERP
¹ though the price gets worse over time; AMM of constant sum such as mStable does not have infinite liquidity
² the range is in fact [-∞,∞], while a price in most cases won’t be negative
³ AMM of constant sum does not have price slippage
2. Tick
The whole innovation of Uniswap v3 starts from ticks.
For those unfamiliar with what is a tick:
Source: https://www.investopedia.com/terms/t/tick.asp
By slicing the price range [0,∞] into numerous granular ticks, trading on v3 is highly similar to trading on order book exchanges, with only three differences:
The price range of each tick is predefined by the system instead of being proposed by users.
Trades that happen within a tick still follows the pricing function of the AMM, while the equation has to be updated once the price crosses the tick.
Orders can be executed with any price within the price range, instead of being fulfilled at the same one price on order book exchanges.
With the tick design, Uniswap v3 possesses most of the merits of both AMM and an order book exchange! 💯💯💯
So, how is the price range of a tick decided?
This question is actually somewhat related to the tick explanation above: the minimum tick size for stocks trading above 1$ is one cent.
The underlying meaning of a tick size traditionally being one cent is that one cent (1% of 1$) is the basis point of price changes between ticks, ex: 1.02 — 1.01 = 0.1.
Uniswap v3 employs a similar idea: compared to the previous/next price, the price change should always be 0.01% = 1 basis point.
However, notice the difference is that in the traditional basis point, the price change is defined with subtraction, while here in Uniswap it’s division.
This is how price ranges of ticks are decided⁴:
Image source: https://uniswap.org/whitepaper-v3.pdf
With the above equation, the tick/price range can be recorded in the index form [i, i+1], instead of some crazy numbers such as 1.0001¹⁰⁰ = 1.0100496621.
As each price is the multiplication of 1.0001 of the previous price, the price change is always 1.0001 — 1 = 0.0001 = 0.01%.
For example, when i=1, p(1) = 1.0001; when i=2, p(2) = 1.00020001.
p(2) / p(1) = 1.00020001 / 1.0001 = 1.0001
See the connection between the traditional basis point 1 cent (=1% of 1$) and Uniswap v3’s basis point 0.01%?

But sir, are prices really granular enough? There are many shitcoins with prices less than 0.000001$. Will such prices be covered as well?
Price range: max & min
To know if an extremely small price is covered or not, we have to figure out the max & min price range of v3 by looking into the spec: there is a int24 tick state variable in UniswapV3Pool.sol.
Image source: https://uniswap.org/whitepaper-v3.pdf
The reason for a signed integer int instead of an uint is that negative power represents prices less than 1 but greater than 0.
24 bits can cover the range between 1.0001 ^ (2²³ — 1) and 1.0001 ^ -(2)²³. Even Google cannot calculate such numbers, so allow me to offer smaller values to have a rough idea of the whole price range:
1.0001 ^ (2¹⁸) = 242,214,459,604.341
1.0001 ^ -(2¹⁷) = 0.000002031888943
I think it’s safe to say that with a int24 the range can cover > 99.99% of the prices of all assets in the universe 👌
⁴ For implementation concern, however, a square root is added to both sides of the equation.
How about finding out which tick does a price belong to?
Tick index from price
The answer to this question is rather easy, as we know that p(i) = 1.0001^i, simply takes a log with base 1.0001 on both sides of the equation⁴:
Image source: https://www.codecogs.com/latex/eqneditor.php
Let’s try this out, say we wanna find out the tick index of 1000000.
Image source: https://ncalculators.com/number-conversion/log-logarithm-calculator.htm
Now, 1.0001¹³⁸¹⁶² = 999,998.678087146. Voila!
⁵ This formula is also slightly modified to fit the real implementation usage.
3. Concentrated liquidity
Now that we know how ticks and price ranges are decided, let’s talk about how orders are executed in a tick, what is concentrated liquidity and how it enables v3 to compete with stablecoin-specialized DEXs (decentralized exchange), such as Curve, by improving the capital efficiency.
Concentrated liquidity means LPs (liquidity providers) can provide liquidity to any price range/tick at their wish, which causes the liquidity to be imbalanced in ticks.
As each tick has a different liquidity depth, the corresponding pricing function x * y = k also won’t be the same!
Each tick has its own liquidity depth. Image source: https://uniswap.org/blog/uniswap-v3/
Mmm… examples are always helpful for abstract descriptions 😂
Say the original pricing function is 100(x) * 1000(y) = 100000(k), with the price of X token 1000 / 100 = 10 and we’re now in the price range [9.08, 11.08].
If the liquidity of the price range [11.08, 13.08] is the same as [9.08, 11.08], we don’t have to modify the pricing function if the price goes from 10 to 11.08, which is the boundary between two ticks.
The price of X is 1052.63 / 95 = 11.08 when the equation is 1052.63 * 95 = 100000.
However, if the liquidity of the price range [11.08, 13.08] is two times that of the current range [9.08, 11.08], balances of x and y should be doubled, which makes the equation become 2105.26 * 220 = 400000, which is (1052.63 * 2) * (110 * 2) = (100000 * 2 * 2).
We can observe the following two points from the above example:
Trades always follow the pricing function x * y = k, while once the price crosses the current price range/tick, the liquidity/equation has to be updated.
√(x * y) = √k = L is how we represent the liquidity, as I say the liquidity of x * y = 400000 is two times the liquidity of x * y = 100000, as √(400000 / 100000) = 2.
What’s more, compared to liquidity on v1 & v2 is always spread across [0,∞], liquidity on v3 can be concentrated within certain price ranges and thus results in higher capital efficiency from traders’ swapping fees!
Let’s say if I provide liquidity in the range [1200, 2800], the capital efficiency will then be 4.24x higher than v2 with the range [0,∞] 😮😮😮 There’s a capital efficiency comparison calculator, make sure to try it out!

It’s worth noticing that the concept of concentrated liquidity was proposed and already implemented by Kyper, prior to Uniswap, which is called Automated Price Reserve in their case.⁵
⁶ Thanks to Yenwen Feng for the information.
4. Range orders: reversible limit orders
As explained in the above section, LPs of v3 can provide liquidity to any price range/tick at their wish. Depending on the current price and the targeted price range, there are three scenarios:
current price < the targeted price range
current price > the targeted price range
current price belongs to the targeted price range
The first two scenarios are called range orders. They have unique characteristics and are essentially fee-earning reversible limit orders, which will be explained later.
The last case is the exact same liquidity providing mechanism as the previous versions: LPs provide liquidity in both tokens of the same value (= amount * price).
There’s also an identical product to the case: grid trading, a very powerful investment tool for a time of consolidation. Dunno what’s grid trading? Check out Binance’s explanation on this, as this topic won’t be covered!
In fact, LPs of Uniswap v1 & v2 are grid trading with a range of [0,∞] and the entry price as the baseline.
Range orders
To understand range orders, we’d have to first revisit how price is discovered on Uniswap with the equation x * y = k, for x & y stand for the amount of two tokens X and Y and k as a constant.
The price of X compared to Y is y / x, which means how many Y one can get for 1 unit of X, and vice versa the price of Y compared to X is x / y.
For the price of X to go up, y has to increase and x decrease.
With this pricing mechanism in mind, it’s example time!
Say an LP plans to place liquidity in the price range [15.625, 17.313], higher than the current price of X 10, when 100(x) * 1000(y) = 100000(k).
The price of X is 1250 / 80 = 15.625 when the equation is 80 * 1250 = 100000.
The price of X is 1315.789 / 76 = 17.313 when the equation is 76 * 1315.789 = 100000.
If now the price of X reaches 15.625, the only way for the price of X to go even higher is to further increase y and decrease x, which means exchanging a certain amount of X for Y.
Thus, to provide liquidity in the range [15.625, 17.313], an LP needs only to prepare 80 — 76 = 4 of X. If the price exceeds 17.313, all 4 X of the LP is swapped into 1315.789 — 1250 = 65.798 Y, and then the LP has nothing more to do with the pool, as his/her liquidity is drained.
What if the price stays in the range? It’s exactly what LPs would love to see, as they can earn swapping fees for all transactions in the range! Also, the balance of X will swing between [76, 80] and the balance of Y between [1250, 1315.789].
This might not be obvious, but the example above shows an interesting insight: if the liquidity of one token is provided, only when the token becomes more valuable will it be exchanged for the less valuable one.
…wut? 🤔
Remember that if 4 X is provided within [15.625, 17.313], only when the price of X goes up from 15.625 to 17.313 is 4 X gradually swapped into Y, the less valuable one!
What if the price of X drops back immediately after reaching 17.313? As X becomes less valuable, others are going to exchange Y for X.
The below image illustrates the scenario of DAI/USDC pair with a price range of [1.001, 1.002] well: the pool is always composed entirely of one token on both sides of the tick, while in the middle 1.001499⁶ is of both tokens.
Image source: https://uniswap.org/blog/uniswap-v3/
Similarly, to provide liquidity in a price range < current price, an LP has to prepare a certain amount of Y for others to exchange Y for X within the range.
To wrap up such an interesting feature, we know that:
Only one token is required for range orders.
Only when the current price is within the range of the range order can LP earn trading fees. This is the main reason why most people believe LPs of v3 have to monitor the price more actively to maximize their income, which also means that LPs of v3 have become arbitrageurs 🤯
I will be discussing more the impacts of v3 in 5. Impacts of v3.
⁷ 1.001499988 = √(1.0001 * 1.0002) is the geometric mean of 1.0001 and 1.0002. The implication is that the geometric mean of two prices is the average execution price within the range of the two prices.
Reversible limit orders
As the example in the last section demonstrates, if there is 4 X in range [15.625, 17.313], the 4 X will be completely converted into 65.798 Y when the price goes over 17.313.
We all know that a price can stay in a wide range such as [10, 11] for quite some time, while it’s unlikely so in a narrow range such as [15.625, 15.626].
Thus, if an LP provides liquidity in [15.625, 15.626], we can expect that once the price of X goes over 15.625 and immediately also 15.626, and does not drop back, all X are then forever converted into Y.
The concept of having a targeted price and the order will be executed after the price is crossed is exactly the concept of limit orders! The only difference is that if the range of a range order is not narrow enough, it’s highly possible that the conversion of tokens will be reverted once the price falls back to the range.
As price ranges follow the equation p(i) = 1.0001 ^ i, the range can be quite narrow and a range order can thus effectively serve as a limit order:
When i = 27490, 1.0001²⁷⁴⁹⁰ = 15.6248.⁸
When i = 27491, 1.0001²⁷⁴⁹¹ = 15.6264.⁸
A range of 0.0016 is not THAT narrow but can certainly satisfy most limit order use cases!
⁸ As mentioned previously in note #4, there is a square root in the equation of the price and index, thus the numbers here are for explantion only.
5. Impacts of v3
Higher capital efficiency, LPs become arbitrageurs… as v3 has made tons of radical changes, I’d like to summarize my personal takes of the impacts of v3:
Higher capital efficiency makes one of the most frequently considered indices in DeFi: TVL, total value locked, becomes less meaningful, as 1$ on Uniswap v3 might have the same effect as 100$ or even 2000$ on v2.
The ease of spot exchanging between spot exchanges used to be a huge advantage of spot markets over derivative markets. As LPs will take up the role of arbitrageurs and arbitraging is more likely to happen on v3 itself other than between DEXs, this gap is narrowed … to what extent? No idea though.
LP strategies and the aggregation of NFT of Uniswap v3 liquidity token are becoming the blue ocean for new DeFi startups: see Visor and Lixir. In fact, this might be the turning point for both DeFi and NFT: the two main reasons of blockchain going mainstream now come to the alignment of interest: solving the $$ problem 😏😏😏
In the right venue, which means a place where transaction fees are low enough, such as Optimism, we might see Algo trading firms coming in to share the market of designing LP strategies on Uniswap v3, as I believe Algo trading is way stronger than on-chain strategies or DAO voting to add liquidity that sort of thing.
After reading this article by Parsec.finance: The Dex to Rule Them All, I cannot help but wonder: maybe there is going to be centralized crypto exchanges adopting v3’s approach. The reason is that since orders of LPs in the same tick are executed pro-rata, the endless front-running speeding-competition issue in the Algo trading world, to some degree, is… solved? 🤔
Anyway, personal opinions can be biased and seriously wrong 🙈 I’m merely throwing out a sprat to catch a whale. Having a different voice? Leave your comment down below!
6. Conclusion
That was kinda tough, isn’t it? Glad you make it through here 🥂🥂🥂
There are actually many more details and also a huge section of Oracle yet to be covered. However, since this article is more about features and targeting normal DeFi users, I’ll leave those to the next one; hope there is one 😅
If you have any doubt or find any mistake, please feel free to reach out to me and I’d try to reply AFAP!
Stay tuned and in the meantime let’s wait and see how Uniswap v3 is again pioneering the innovation of DeFi 🌟

The President’s Executive Order on Hong Kong Normalization
Issued on: July 14, 2020
By the authority vested in me as President by the Constitution and the laws of the United States of America, including the United States-Hong Kong Policy Act of 1992 (Public Law 102-393), the Hong Kong Human Rights and Democracy Act of 2019 (Public Law 116-76), the Hong Kong Autonomy Act of 2020, signed into law July 14, 2020, the International Emergency Economic Powers Act (50 U.S.C. 1701 et seq.) (IEEPA), the National Emergencies Act (50 U.S.C. 1601 et seq.) (NEA), section 212(f) of the Immigration and Nationality Act of 1952 (8 U.S.C. 1182(f)), and section 301 of title 3, United States Code,
I, DONALD J. TRUMP, President of the United States of America, determine, pursuant to section 202 of the United States-Hong Kong Policy Act of 1992, that the Special Administrative Region of Hong Kong (Hong Kong) is no longer sufficiently autonomous to justify differential treatment in relation to the People’s Republic of China (PRC or China) under the particular United States laws and provisions thereof set out in this order. In late May 2020, the National People’s Congress of China announced its intention to unilaterally and arbitrarily impose national security legislation on Hong Kong. This announcement was merely China’s latest salvo in a series of actions that have increasingly denied autonomy and freedoms that China promised to the people of Hong Kong under the 1984 Joint Declaration of the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the People’s Republic of China on the Question of Hong Kong (Joint Declaration). As a result, on May 27, 2020, the Secretary of State announced that the PRC had fundamentally undermined Hong Kong’s autonomy and certified and reported to the Congress, pursuant to sections 205 and 301 of the United States-Hong Kong Policy Act of 1992, as amended, respectively, that Hong Kong no longer warrants treatment under United States law in the same manner as United States laws were applied to Hong Kong before July 1, 1997. On May 29, 2020, I directed the heads of executive departments and agencies (agencies) to begin the process of eliminating policy exemptions under United States law that give Hong Kong differential treatment in relation to China.
China has since followed through on its threat to impose national security legislation on Hong Kong. Under this law, the people of Hong Kong may face life in prison for what China considers to be acts of secession or subversion of state power –- which may include acts like last year’s widespread anti-government protests. The right to trial by jury may be suspended. Proceedings may be conducted in secret. China has given itself broad power to initiate and control the prosecutions of the people of Hong Kong through the new Office for Safeguarding National Security. At the same time, the law allows foreigners to be expelled if China merely suspects them of violating the law, potentially making it harder for journalists, human rights organizations, and other outside groups to hold the PRC accountable for its treatment of the people of Hong Kong.
I therefore determine that the situation with respect to Hong Kong, including recent actions taken by the PRC to fundamentally undermine Hong Kong’s autonomy, constitutes an unusual and extraordinary threat, which has its source in substantial part outside the United States, to the national security, foreign policy, and economy of the United States. I hereby declare a national emergency with respect to that threat.
In light of the foregoing, I hereby determine and order:
Section 1. It shall be the policy of the United States to suspend or eliminate different and preferential treatment for Hong Kong to the extent permitted by law and in the national security, foreign policy, and economic interest of the United States.
Sec. 2. Pursuant to section 202 of the United States-Hong Kong Policy Act of 1992 (22 U.S.C. 5722), I hereby suspend the application of section 201(a) of the United States-Hong Kong Policy Act of 1992, as amended (22 U.S.C. 5721(a)), to the following statutes:
(a) section 103 of the Immigration Act of 1990 (8 U.S.C. 1152 note);
(b) sections 203(c), 212(l), and 221(c) of the Immigration and Nationality Act of 1952, as amended (8 U.S.C. 1153(c), 1182(l), and 1201(c), respectively);
(c) the Arms Export Control Act (22 U.S.C. 2751 et seq.);
(d) section 721(m) of the Defense Production Act of 1950, as amended (50 U.S.C. 4565(m));
(e) the Export Control Reform Act of 2018 (50 U.S.C. 4801 et seq.); and
(f) section 1304 of title 19, United States Code.
Sec. 3. Within 15 days of the date of this order, the heads of agencies shall commence all appropriate actions to further the purposes of this order, consistent with applicable law, including, to:
(a) amend any regulations implementing those provisions specified in section 2 of this order, and, consistent with applicable law and executive orders, under IEEPA, which provide different treatment for Hong Kong as compared to China;
(b) amend the regulation at 8 CFR 212.4(i) to eliminate the preference for Hong Kong passport holders as compared to PRC passport holders;
(c) revoke license exceptions for exports to Hong Kong, reexports to Hong Kong, and transfers (in-country) within Hong Kong of items subject to the Export Administration Regulations, 15 CFR Parts 730-774, that provide differential treatment compared to those license exceptions applicable to exports to China, reexports to China, and transfers (in-country) within China;
(d) consistent with section 902(b)(2) of the Foreign Relations Authorization Act, Fiscal Years 1990 and 1991 (Public Law 101-246), terminate the export licensing suspensions under section 902(a)(3) of such Act insofar as such suspensions apply to exports of defense articles to Hong Kong persons who are physically located outside of Hong Kong and the PRC and who were authorized to receive defense articles prior to the date of this order;
(e) give notice of intent to suspend the Agreement Between the Government of the United States of America and the Government of Hong Kong for the Surrender of Fugitive Offenders (TIAS 98-121);
(f) give notice of intent to terminate the Agreement Between the Government of the United States of America and the Government of Hong Kong for the Transfer of Sentenced Persons (TIAS 99-418);
(g) take steps to end the provision of training to members of the Hong Kong Police Force or other Hong Kong security services at the Department of State’s International Law Enforcement Academies;
(h) suspend continued cooperation undertaken consistent with the now-expired Protocol Between the U.S. Geological Survey of the Department of the Interior of the United States of America and Institute of Space and Earth Information Science of the Chinese University of Hong Kong Concerning Scientific and Technical Cooperation in Earth Sciences (TIAS 09-1109);
(i) take steps to terminate the Fulbright exchange program with regard to China and Hong Kong with respect to future exchanges for participants traveling both from and to China or Hong Kong;
(j) give notice of intent to terminate the agreement for the reciprocal exemption with respect to taxes on income from the international operation of ships effected by the Exchange of Notes Between the Government of the United States of America and the Government of Hong Kong (TIAS 11892);
(k) reallocate admissions within the refugee ceiling set by the annual Presidential Determination to residents of Hong Kong based on humanitarian concerns, to the extent feasible and consistent with applicable law; and
(l) propose for my consideration any further actions deemed necessary and prudent to end special conditions and preferential treatment for Hong Kong.
Sec. 4. All property and interests in property that are in the United States, that hereafter come within the United States, or that are or hereafter come within the possession or control of any United States person, of the following persons are blocked and may not be transferred, paid, exported, withdrawn, or otherwise dealt in:

(iv) to have materially assisted, sponsored, or provided financial, material, or technological support for, or goods or services to or in support of, any person whose property and interests in property are blocked pursuant to this section;
(v) to be owned or controlled by, or to have acted or purported to act for or on behalf of, directly or indirectly, any person whose property and interests in property are blocked pursuant to this section; or
(vi) to be a member of the board of directors or a senior executive officer of any person whose property and interests in property are blocked pursuant to this section.
(b) The prohibitions in subsection (a) of this section apply except to the extent provided by statutes, or in regulations, orders, directives, or licenses that may be issued pursuant to this order, and notwithstanding any contract entered into or any license or permit granted before the date of this order.
Sec. 5. I hereby determine that the making of donations of the types of articles specified in section 203(b)(2) of IEEPA (50 U.S.C. 1702(b)(2)) by, to, or for the benefit of any person whose property and interests in property are blocked pursuant to section 4 of this order would seriously impair my ability to deal with the national emergency declared in this order, and I hereby prohibit such donations as provided by section 4 of this order.
Sec. 6. The prohibitions in section 4(a) of this order include:
(a) the making of any contribution or provision of funds, goods, or services by, to, or for the benefit of any person whose property and interests in property are blocked pursuant to section 4(a) of this order; and
(b) the receipt of any contribution or provision of funds, goods, or services from any such person.
Sec. 7. The unrestricted immigrant and nonimmigrant entry into the United States of aliens determined to meet one or more of the criteria in section 4(a) of this order, as well as immediate family members of such aliens, or aliens determined by the Secretary of State to be employed by, or acting as an agent of, such aliens, would be detrimental to the interest of the United States, and the entry of such persons into the United States, as immigrants and nonimmigrants, is hereby suspended. Such persons shall be treated as persons covered by section 1 of Proclamation 8693 of July 24, 2011 (Suspension of Entry of Aliens Subject to United Nations Security Council Travel Bans and International Emergency Economic Powers Act Sanctions). The Secretary of State shall have the responsibility of implementing this section pursuant to such conditions and procedures as the Secretary has established or may establish pursuant to Proclamation 8693.
Sec. 8. (a) Any transaction that evades or avoids, has the purpose of evading or avoiding, causes a violation of, or attempts to violate any of the prohibitions set forth in this order is prohibited.
(b) Any conspiracy formed to violate any of the prohibitions set forth in this order is prohibited.
Sec. 9. Nothing in this order shall prohibit transactions for the conduct of the official business of the Federal Government by employees, grantees, or contractors thereof.
Sec. 10. For the purposes of this order:
(a) the term “person” means an individual or entity;
(b) the term “entity” means a government or instrumentality of such government, partnership, association, trust, joint venture, corporation, group, subgroup, or other organization, including an international organization;
(c) the term “United States person” means any United States citizen, permanent resident alien, entity organized under the laws of the United States or any jurisdiction within the United States (including foreign branches), or any person in the United States; and
(d) The term “immediate family member” means spouses and children of any age.
Sec. 11. For those persons whose property and interests in property are blocked pursuant to this order who might have a constitutional presence in the United States, I find that because of the ability to transfer funds or other assets instantaneously, prior notice to such persons of measures to be taken pursuant to section 4 of this order would render those measures ineffectual. I therefore determine that for these measures to be effective in addressing the national emergency declared in this order, there need be no prior notice of a listing or determination made pursuant to section 4 of this order.
Sec. 12. The Secretary of the Treasury, in consultation with the Secretary of State, is hereby authorized to take such actions, including adopting rules and regulations, and to employ all powers granted to me by IEEPA as may be necessary to implement this order. The Secretary of the Treasury may, consistent with applicable law, redelegate any of these functions within the Department of the Treasury. All departments and agencies of the United States shall take all appropriate measures within their authority to implement this order.
Sec. 13. The Secretary of the Treasury, in consultation with the Secretary of State, is hereby authorized to submit recurring and final reports to the Congress on the national emergency declared in this order, consistent with section 401(c) of the NEA (50 U.S.C. 1641(c)) and section 204(c) of IEEPA (50 U.S.C. 1703(c)).
Sec. 14. (a) Nothing in this order shall be construed to impair or otherwise affect:
(i) the authority granted by law to an executive department or agency; or
(ii) the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.
(b) This order shall be implemented consistent with applicable law and subject to the availability of appropriations.
(c) This order is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.
Sec. 15. If, based on consideration of the terms, obligations, and expectations expressed in the Joint Declaration, I determine that changes in China’s actions ensure that Hong Kong is sufficiently autonomous to justify differential treatment in relation to the PRC under United States law, I will reconsider the determinations made and actions taken and directed under this order.

【Simple banana donut in a plastic bag】
Today, I made a "banana donut" that uses a plastic bag to minimize washing and keep hands clean.
It's easy, but the taste is outstanding! The outside is crispy, the inside is fluffy, and the sweetness of the banana stands out to make it a delicious finish.
The dough can be made simply by putting all the ingredients in a plastic bag, so it's really easy! It is easy to fry it because it can be done with a small amount of oil in a frying pan!
Since it is a recommended hand-made recipe which omitted all the troublesome processes, please feel free to try it by all means.
〈INGREDIENT〉
One banana (100g)
1 egg
Pan cake mix 150g

【Creme Dunge】
Today, I made a "Creme Dunge" that can be easily and easily made with three ingredients.
Creme d'Ange is a kind of French cheesecake, also known as a fluffy angelic cream melter with a fluffy texture that melts into a fallen angel.
Originally, I used fresh cheese called fromage jub, but I tried to make it as an easy recipe that you can feel free even at home by using a drained yogurt.
It is certain that it will melt in a moment in a thick and unbearable taste even though it is fluffy! ! By all means, it is a sweet that you want to try for those who like cheese cake.

0:50 To get started is what is a candlestick pattern? Okay, so a candlestick pattern is essentially a method, right? Of reading a price chart. It originated back in Japan, right? That's the history. And the key component of a candlestick chart is that it shows you four things. It shows you the opening price, the price, the high of the session, the low of the session and the closing price,
2:00 How do you read a candlestick pattern? Or how do you read a candlestick chart? So remember there are only four things, the open, the high, the low, and the close. You can see that the candles are usually typically two colors, either you know, green, red, or perhaps it can be black, white. Sometimes you can even you know, change the color if you want, but generally, the most common color is green and red.
9:00 So now, I want to walk you through something what we call combining candlestick patterns. Because candlestick patterns, they are essentially just showing you the price of the different sessions. And if you think about this, right? This can be combined, right?
12:48 So now, how not to trade candlestick patterns, right? So now you know how to read candlestick pattern, you even know how to combine them, how do you not trade candlestick patterns? Because this is a mistake.
15:00 So how should you trade candlestick patterns? I would like to introduce to you something what I call the TAE framework. The TAE TAE framework, alright? So what is TAE? TAE stands for Trend, right? A is Area of value, and E stands for Entry trigger.
16:00 The engulfing pattern, right? This is the so called the theory behind it, right? So you can see that this green candle over here is what we call the bullish engulfing pattern. Why is that? Because if you look at it, right? The body of the green candle which is the... From here in the open and the close, it has engulfed the body of the previous candle.
18:00 Hammer and shooting star. Alright, so let's have a look at the hammer. So the hammer is something that you might be familiar with because you saw earlier, right? The earlier examples. So the hammer is a bullish reversal, because it's actually showing you price rejection in the market. In fact, it's rejection of lower prices.
19:20 Dragonfly and a Gravestone Doji, right? Sounds a handful but really the method is very similar to the hammer and shooting star. The only difference, right? Is that now this Doji. Doji simply means, right? A indecision in the markets. But for Dragonfly and Gravestone Doji, it's a sign of price rejection.
20:45 Morning and evening star. Red star, let's look at the star. So this is a morning star, so you can see that this is somewhat similar to the engulfing pattern, but with a slight variation to it. First candle, sellers are in control. Open over here and closing near the lows.
23:00 Finally Tweezer Top and Bottom, right? So a Tweezer Top, right? Is this one over here, okay? So this actually a Tweezer Bottom.
24:26 How does this fit into the TAE framework, right? Remember the TAE, right? Trend, Area of value, and the Entry trigger. So now we have really settle the entry trigger portion because the reversal patterns that you have seen earlier, those are entry triggers that you can use to enter the trade. But before you, you know, you trade it right? Remember we said, right? Don't trade it in isolation. This means that we have to use other factors or other market conditions, right?
