In the TRTH Time and Sales Extraction, we are extracting data with the field Trade - Qualifiers
1. Is there any documentations on all the types of qualifiers for each trade?
2. We are specifically trying to identify trades that are made by the market makers, as we knew in the past that we should be looking for "[ACT_FLAG1]" flag inside the Trade - Qualifiers field. Is this flag consistent for different exchanges?
