## Calculation Breakdown

Please correct me if I'm wrong

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

• Refer to Uniswap V3 Whitepaper (Formula: 6.29, 6.30, P.8), we can calculate total amounts of each token by using these formulas: (if `il <= ic < iu`; where `il` = lowerTickId, `ic` = currentTickId, `iu` = upperTickId)
• `deltaY = deltaL * (sqrt(P) - sqrt(Pl))`
• `deltaX = deltaL * (1 / sqrt(P) - 1 / sqrt(Pu))`
• For estimation of the amounts of token0 (`deltaX`) and token1 (`deltaY`) we need to know `deltaL` that make:
• `deltaY * priceUSDY + deltaX * priceUSDX = targetAmounts`
• So we can write a equation like this:
• `deltaL * (sqrt(P) - sqrt(Pl)) * priceUSDY + deltaL * (1 / sqrt(P) - 1 / sqrt(Pu)) * priceUSDX = targetAmounts`
• Then: `deltaL = targetAmounts / (sqrt(P) - sqrt(Pl)) * priceUSDY + (1 / sqrt(P) - 1 / sqrt(Pu)) * priceUSD`
• 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 - 4, 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)`
