Price granularity change
Matching had introduced PIP size for specific instrument pairs(for MXN, RUB and ZAR). PIP size for these instruments will be 0.0005 and only 0 or 5 will be allowed values for the 4th decimal place. If the client submits a price for above instruments in a wrong format that is, 4th decimal place is not 0/5 then adapter will round the price.
Example:
Price 12.078123 is changed to 12.0785
price 8.981234 is changed to 8.9815
Price 8.979567 is changed to 8.9800
You receive PIP value in Reference model. PIP value gets updated every time IAF starts or there is a notification from Matching that trading mode changed from disabled to active. User need not worry about updating it. The following interfaces are supported:
com.apama.fix.mapi.PipSize {string TRANSPORT;string symbol;string pip;}
where symbol is the instrument name and pip is the PIP size.
Client can use this event in case there is a change to current PIP values. You will not be releasing MAPI whenever there is a change to PIP value.
