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?
The qualifier codes are provided by the exchange, and these codes may differ from exchange to exchange as well as the asset class.
The document for each exchange and asset class can be found on the following link.
