I do get a value ("C ")returned for index .HSI (Hang Seng) , .IXIC (Nasdaq) but no value is getting returned for rics like .N225 (which is Nikkei 225), .BSESN, .SPX (which is SP500). Can you tell me why this behavior is not consistent across RICS . Also does "C " indicate a market close . What value is returned when the market is opened .

Hi @calvin.k

Basically, Each RIC and Exchange’s has it own data behavior which is based on the contributor, the actual trading, etc. The Field/Fid's behavior and meaning are not consistent across exchanges, it based on it own exchange. The application should not apply one exchange behavior to other exchanges.

Hi @calvin.k

I recommend you contact our Data Content experts for guidance on exchange / asset specific behaviour.
