TradeStation Help
The trigger type allows you to specify the type of tick, number, and pattern of ticks that will trigger a specific row of an activation rule. Bid/Ask and Ask/Bid triggers use the comparison operator (>/>= or </<=) for the row to determine which type of tick to compare. Double refers to two consecutive ticks and Twice refers to two non-consecutive ticks in the same day.
