Can someone please help me with some documentation to explain what values need to set for RECORDTYPE(FID: 259) for different Asset classes.
I believe this needs to be 209 for Chains. Is that correct?
Refer to the Using FID 259 to identify your market data records article to better understand how this FID is used.
For the FID 259 = 209, it maps to a "Forex - Foreign Exchange" / "cash instrument".
