TRO DOPC & TRO BUY ZONE

FORM-T TRADES REAR THEIR UGLY HEAD
TRO DOPC & TRO BUY ZONE
Since I can't trade on TradeStation, I forgot about the FORM T consolidated data stream chart problem.
My indicators were using OpenD(0) for the daily open and CloseD(1) for the previous close. Most days this is not a problem. But today in my chatroom, my indicators were showing AAPL opened at $84.25 when in fact, the real NASDAQ open for AAPL was $84.44.
Premarket trades are labeled FORM-T. That indicates a premarket/postmarket trade. But because TradeStation uses a consolidated data stream, FORM-T trades are mixed in with the regular trades. Sometimes, at the open, a FORM-T trade may "sliip in" before the first regular trade and the OpenD(0) value is INCORRECT. This cost me a lot of money years ago, when I was running AutoAvery.
Since 8.1, indicators can reference the quote fields DAILYOPEN and PREVIOUS CLOSE and those values are "correct".
The TRO_DOPC indicator replaces _DailyOpenPrevClose.
The TRO_BuyZone indicator replaces _BuyZone.
Both use DAILYOPEN and PREVIOUS CLOSE.
ELD attached.
