NonfungiblePositionManager Contract in Uniswap V3

When we add liquidity to the Uniswap V3 liquidity pool (trading pair pool), the NonfungiblePositionManager contract returns a minted NFT to us as proof of the liquidity addition.

The first step is to use the router contract to get the address of the corresponding NonfungiblePositionManager contract, and then use the balanceOf method of the NonfungiblePositionManager contract to get the number of position NFTs for the specified wallet address.

Then use the tokenOfOwnerByIndex method to get the tokenId of these position NFTs, with these tokenId, you can use the positions method to continue to query the specific details of these positions.

The following test code:

```

Parsing Liquidity Holdings for Market Making Ranges

The positions method of Uniswap's NonfungiblePositionManager contract returns tickLower and tickUpper in the liquidity position data. In Uniswap V3, liquidity can be specified within a range, whereas the initial design of Uniswap had uniform distribution of liquidity. The specification of a liquidity range in subsequent versions is aimed at improving the utilization of liquidity capital.

> tickLower: The lower end of the tick range for the position
> tickUpper: The higher end of the tick range for the position

tickLower and tickUpper represent the upper and lower limits of the liquidity. Referring to the Uniswap documentation and its complex formulas, tickLower and tickUpper are essentially price boundaries recorded in exponential form. So, how can we calculate the price range for market-making from these "exponential boundaries"?

It's quite simple. Uniswap uses a base of ```1.0001```. Lower price: ```lowerPrice = 1.0001 ** tickLower```; Upper price: ```upperPrice = 1.0001 ** tickUpper```. The ```**``` operator represents exponentiation. For example, ```1.0001 ** 100``` calculates 1.0001 raised to the power of 100.

This calculated price range is denominated in token1. But what if we want to see the price range denominated in token0?

It can be calculated as follows:
Lower price: 1.0001 ** -tickUpper
Upper price: 1.0001 ** -tickLower

Compare this to the NFT position we looked up on the chain:

Parsing the Asset Value in the Current Liquidity Position

In addition to tickUpper and tickLower, the positions method of Uniswap's NonfungiblePositionManager contract returns another important data: liquidity.

By combining the liquidity, tickUpper, tickLower data from the position information with the current price data in the exchange pool, we can calculate the asset value in the current liquidity position.

You may wonder why we need to know the current price in the exchange pool to make the calculation.

This is because once you add liquidity, any price changes within the effective range of your liquidity position imply that your assets have been exchanged. If the current exchange price is not within the effective range of your liquidity provision, there won't be any changes. Therefore, there are three scenarios to consider when calculating:

- The tick of the current price is less than tickLower.
- The tick of the current price is greater than tickUpper.
- The tick of the current price is within the range of tickLower to tickUpper.

This corresponds to the following calculation and processing in the code:

```
if (currentTick <= posData.tickLower) {
amount0wei = Math.floor(posData.liquidity * ((sqrtRatioB - sqrtRatioA) / (sqrtRatioA * sqrtRatioB)))
} else if (currentTick > posData.tickUpper) {
amount1wei = Math.floor(posData.liquidity * (sqrtRatioB - sqrtRatioA))
} else if (currentTick >= posData.tickLower && currentTick < posData.tickUpper) {
amount0wei = Math.floor(posData.liquidity * ((sqrtRatioB - sqrtPrice) / (sqrtPrice * sqrtRatioB)))
amount1wei = Math.floor(posData.liquidity * (sqrtPrice - sqrtRatioA))
}
```

To perform the above calculations, we need to obtain the tick of the current price, which can be obtained directly from the pool contract. To get the address of the pool contract, we can use the getPool method of Uniswap's factory contract. By using the ```slot0``` method of the pool contract, we can retrieve the current price information, including the tick value we need.
