VALIDITY LIMITATION (Oct 14): the V2 stop distance, size and skip check use ATR measured at the ENTRY bar, which includes that bar's own range - a lookahead that is not knowable at the entry-bar open. This affects the 32-trade backtest and every forward trade here. Simulation only; these results are NOT live-executable expectancy. Rules stay frozen for the sample; a signal-bar ATR variant is tracked separately as exploratory. Sep 21 is held for a data check; Oct 13 was corrected (+$15.71, original values kept in its audit note).
