Post From: CME trade-type metadata

Does Sierra Chart / Denali preserve CME trade-type metadata for off-book or negotiated transactions such as Block Trades, EFP/EFRP/EFS, and is this information exposed through ACSIL?

In particular, is there any field in `s_TimeAndSales`, intraday file records, or another ACSIL structure equivalent to a trade condition / OTC trade type flag?

The purpose is to exclude negotiated/off-book trades from a custom Time & Sales aggregation study, rather than infer them from volume or execution pattern.

Thanks
