## Features

- Fee calculation: select pair and pool, input deposit amount (USD), and adjust your lower and upper price

- Liquidity position histogram and correlation chart to help you plan your strategy better

- It's 100% open source! hope that Uniswap community will bring a lot more ideas and features to this project

## Calculation Breakdown

### 1. Calculate deposit amount of token0 and token1

- Refer to [Uniswap V3 Whitepaper](https://uniswap.org/whitepaper-v3.pdf) (Formula: 6.29, 6.30, P.8), we can calculate total amount of each token by using these formulas: (if `il <= ic < iu`; where `il` = lowerTickId, `ic` = currentTickId, `iu` = upperTickId, `Pl` = lower price, `Pu` = upper price)

  - `deltaY = deltaL * (sqrt(P) - sqrt(Pl))`

  - `deltaX = deltaL * (1 / sqrt(P) - 1 / sqrt(Pu))`

- For estimation of the amount of token0 (`deltaX`) and token1 (`deltaY`) we need to know `deltaL` that make:

  - `deltaY * priceUSDY + deltaX * priceUSDX = depositAmountUSD`

- So we can write a equation like this:

  - `deltaL * (sqrt(P) - sqrt(Pl)) * priceUSDY + deltaL * (1 / sqrt(P) - 1 / sqrt(Pu)) * priceUSDX = depositAmountUSD`

  - Then: `deltaL = depositAmountUSD / ((sqrt(P) - sqrt(Pl)) * priceUSDY + (1 / sqrt(P) - 1 / sqrt(Pu)) * priceUSDX)`

- After we've calculated `deltaL`, we can calculate `deltaX` and `deltaY` using these formulas mentioned in Uniswap v3 Whitepaper

  - `deltaY = deltaL * (sqrt(P) - sqrt(Pl))` (Formula: 6.29, P.8)

  - `deltaX = deltaL * (1 / sqrt(P) - 1 / sqrt(Pu))` (Formula: 6.30, P.8)

### 2. Calculate estimated fee

- Estimated fee (daily) can be calculated by this equation:

  - `fee = feeTier * volume24H * (deltaL / (L + deltaL))` where:

    - `volume24H` = average of 24h volume from `[currentDay - 7, currentDay - 1]`

    - `L` = total liquidity (cumulative of `liquidityNet` from all ticks that `il <= ic`)

    - `deltaL` = delta liquidity, can be calculated from:

      - `liquidityAmount0 = amount0 * (sqrt(pu) * sqrt(pl)) / (sqrt(pu) - sqrt(pl))`

      - `liquidityAmount1 = amount1 / (sqrt(pu) - sqrt(pl))`

      - if `ic < il`; `deltaL = liquidityAmount0`

      - if `ic > iu`; `deltaL = liquidityAmount1`

      - if `ic >= il && ic <= iu`; `deltaL = min(liquidityAmount0, liquidityAmount1)`
