Specifies how a strategy exits positions when the ExitStop formula is used
Intraday - ExitStop specifies the price of a live stop order to be placed each day (default)
AtClose - exit at the close if the closing price touches or exceeds the ExitStop price
AtOpen - exit at the open if the most recent closing price touched or exceeded the ExitStop price
For a long position, an AtClose ExitStop at price N is equivalent to an ExitRule of "C <= N" with ExitTime of AtClose.
For a long position, an AtOpen ExitStop at price N is equivalent to an ExitRule of "C <= N" with ExitTime of AtOpen (or unspecified).
The main purpose ExitStopTime is to enable trailing at-close-only stop orders using PrevExitStop.
