The DTC protocol server in Sierra Chart:
https://www.sierrachart.com/index.php?page=doc/DTCServer.php

No longer provides the s_MarketDepthUpdateLevelCompact message and has now replaced it with s_MarketDepthUpdateLevelFloatWithMilliseconds. Since the introduction of the s_MarketDepthUpdateLevelFloatWithMilliseconds message, it was possible to request the use of this new message type instead of s_MarketDepthUpdateLevelCompact by specifying this flag with the Integer_1 field in the s_LogonRequest message:
const unsigned int DTC_LOGON_REQUEST_INTEGER_1_USE_MARKET_DEPTH_UPDATE_FLOAT_WITH_MS_MESSAGES = 0x80;

However, since this message type is so much better, it is now the default. We feel this is long overdue. Any client which is using this DTC server, will need to be updated to use this message.
