Methods

Static invertPrice

  • invertPrice(price: Decimal, decimalsA: number, decimalsB: number): Decimal

  • Utility to invert the price Pb/Pa to Pa/Pb NOTE: precision is lost in this conversion

    Parameters

    • price: Decimal

      Pb / Pa

    • decimalsA: number

      Decimals of original token A (i.e. token A in the given Pb / Pa price)

    • decimalsB: number

      Decimals of original token B (i.e. token B in the given Pb / Pa price)

    Returns Decimal

    inverted price, i.e. Pa / Pb

Static invertSqrtPriceX64

  • invertSqrtPriceX64(sqrtPriceX64: BN): BN

  • Utility to invert the sqrtPriceX64 from X64 repr. of sqrt(Pb/Pa) to X64 repr. of sqrt(Pa/Pb) NOTE: precision is lost in this conversion

    Parameters

    • sqrtPriceX64: BN

      X64 representation of sqrt(Pb / Pa)

    Returns BN

    inverted sqrtPriceX64, i.e. X64 representation of sqrt(Pa / Pb)

Static priceToInitializableTickIndex

  • priceToInitializableTickIndex(price: Decimal, decimalsA: number, decimalsB: number, tickSpacing: number): number

Static priceToSqrtPriceX64

  • priceToSqrtPriceX64(price: Decimal, decimalsA: number, decimalsB: number): BN

Static priceToTickIndex

  • priceToTickIndex(price: Decimal, decimalsA: number, decimalsB: number): number

Static sqrtPriceX64ToPrice

  • sqrtPriceX64ToPrice(sqrtPriceX64: BN, decimalsA: number, decimalsB: number): Decimal

Static sqrtPriceX64ToTickIndex

  • sqrtPriceX64ToTickIndex(sqrtPriceX64: BN): number

Static tickIndexToPrice

  • tickIndexToPrice(tickIndex: number, decimalsA: number, decimalsB: number): Decimal

Static tickIndexToSqrtPriceX64

  • tickIndexToSqrtPriceX64(tickIndex: number): BN
