NDF Fixing Date business days should refer to the non-deliverable currency

Fixing date Should use holiday calendar based on the Non Deliverable Currency only

Details of the issue: In the example attached you can see a standard NDF deal, USD/IDR. With IDR being the Non-Deliverable currency.
The instrument setup for the NDF Standard instrument has the fixing date -2BD before the value date, therefore since the valued date is the 15^th^ Nov (Monday), ISAG was expecting the Fixing date to be 11^th^ Nov (Thurs).
Issue: 11^th^ NOV is a holiday for USD so the system flags it as NBD even if it is not an holiday for IDR

CHANGE REQUEST: Business days for the fixing date should always refer to the NON-DELIVERABLE CURRENCY (IDR) and NOT the DELIVERABLE CCY (USD). This is the correct market standard according to IKEA.

AS-IS: Currently Quantum is using the DELIVERABLE CCY (USD) to define the BD for Fixing (and this is also stated in the Help file)
