Thank you.

I have been using this one for a while.
DTC_LOGON_REQUEST_INTEGER_1_USE_MARKET_DEPTH_UPDATE_FLOAT_WITH_MS_MESSAGES = 0x80

These others, below, are new to me. I'm a little afraid of breaking stuff that is already working and debugged. I cannot seem to find any documentation about what these flags change. Could you let me know which messages are impacted or changed by these, and how?

DTC_LOGON_REQUEST_INTEGER_1_SUPPORT_UNBUNDLED_TRADES = 0x4
DTC_LOGON_REQUEST_INTEGER_1_SUPPORT_MARKET_DEPTH_SNAPSHOT_LEVEL_FLOAT = 0x800
DTC_LOGON_REQUEST_INTEGER_1_SUPPORT_MARKET_DATA_UPDATE_TRADE_WITH_UNBUNDLED_INDICATOR_2 = 0x80000
DTC_LOGON_REQUEST_INTEGER_1_SUPPORT_MARKET_DATA_UPDATE_BIDASK_MICROSECOND_MESSAGE = 0x100000
