Bull / Bear 180°
Signal Quality Lab.

Fixed entry rules: Large first-candle body ≥ threshold × prior ATR14; the second 2m candle body-engulfs it in the opposite color. LONG: both candles entirely above SMA20/SMA200. SHORT: both entirely below. Enter on the next 2m open; original stop at the two-candle extreme; fixed take profit at 2R; forced exit after 15 bars (30 minutes by default).
Four stop rules: A original stop only; B move to entry after any favorable excursion; C after +0.5R; D after +1R. R is the initial executed entry-to-stop price distance. Breakeven activates only from the following 2m bar because intrabar sequencing is unknown. Original stop applies until then; stop wins if stop and target touch in one bar. All four replay the same baseline entry timestamps. Position quantity depends on each scenario's remaining equity.

Method: Signals are detected only when the second 2-minute candle has closed. Entry reference is the next 2m candle OPEN. Measure signed future price changes at 2 / 5 / 10 / 20 / 30 minutes using real 1m opens, irrespective of stops or position overlap. Favorable and adverse excursions use real 1m high/low over 30 minutes. A separate subset removes all signals less than 30 minutes after the preceding retained signal. Fixed taker+slippage costs are shown as a hypothetical round-trip entry/exit, not a realized trade. Sampling can overstate significance; confidence intervals are exploratory, UTC-day bootstrapped, and do not correct multiple tests.
