Liquidity correlation calculation

1. Liquidity to CoinAmount

Method: ClmmPoolUtil.getCoinAmountFromLiquidity

Example

const pool = await sdk.Pool.getPool(poolAddress)

const position = await sdk.Position.getSimplePosition(positionAddress)

const lowerSqrtPrice = TickMath.tickIndexToSqrtPriceX64(position.tick_lower_index)
const upperSqrtPrice = TickMath.tickIndexToSqrtPriceX64(position.tick_upper_index)


const liquidity = new BN(position.liquidity)
const curSqrtPrice = new BN(pool.current_sqrt_price)

const lowerSqrtPrice = TickMath.tickIndexToSqrtPriceX64(position.tick_lower_index)
const upperSqrtPrice = TickMath.tickIndexToSqrtPriceX64(position.tick_upper_index)

const amounts = ClmmPoolUtil.getCoinAmountFromLiquidity(
  liquidity,
  curSqrtPrice,
  lowerSqrtPrice,
  upperSqrtPrice,
  false
)

const {coinA, coinB} = amounts

2. Price to TickIndex

when you want to open position, you dont know how to set your tick_lower and tick_upper.

use /src/math/tick.ts TickMath.priceToTickIndex()

// decimalsA and decimalsB means the decimal of coinA and coinB
const tick_lower = TickMath.priceToTickIndex(price, decimalsA, decimalsB)

3. Calculate price from sqrt price

use /src/math/tick.ts TickMath.sqrtPriceX64ToPrice()

const pool = await sdk.Pool.getPool(poolAddress)
const price = TickMath.sqrtPriceX64ToPrice(new BN(pool.current_sqrt_price))
