Interface PrecisionManager

public interface PrecisionManager
To provide an implementation of this class please see BarracudaOverridesModule

Instances of this class are invoked when the spot rate dps is required. Such a dps is not always present during the exchange of messages between the adapter and the Barracuda OMS and needs to be provided so that parts of the spec that require a spot rate DPS, have that information at hand when required.

  • Method Details

    • getSpotRateDPS

      int getSpotRateDPS(String currencyPair)
      Should return the precision of the spot rate, quoted as the 'scale' of the value: the number of significant figures to the right of the spot rate's decimal point.
      Parameters:
      currencyPair -
      Returns:
      Precision of the spot rate, quoted as the 'scale' of the value: the number of significant figures to the right of the spot rate's decimal point.

    • getSpotRatePipMultiplier

      int getSpotRatePipMultiplier(String currencyPair)
      This is the standard number of decimal places for a rate. This is the value userd to convert to and from a pips value. It is also the number of decimals you would round for display assuming no fractional pips.

      eg. if 4 precision = (10^-4 = 0.0000)

      Parameters:
      currencyPair -

    • getAmountDPS

      int getAmountDPS(String currency)
      Should return the precision of an amount/quantity, quoted as the 'scale' of the value: the number of significant figures to the right of the quantity's decimal point.
      Parameters:
      currency -
      Returns:
      Precision of the quantity, quoted as the 'scale' of the value: the number of significant figures to the right of the quantity's decimal point.
