Daily bars (2 held / 5)

Day 0 is the alert bar — alert fired during the session and the rest of the day is a partial hold; it counts in the stats. (Intraday high/low may be slightly inflated by ticks from before the alert fired, but the daily bar is the closest approximation we have to your trade-outcome range.)
