Calculation Breakdown

1. Calculate deposit amount of token0 and token1

• Refer to Uniswap V3 Whitepaper (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)
