Engulfing candle self-test, 2026-10-21T19:46:44.599Z

1. Hand-worked bars (after 520 flat warm-up bars at 2000)
A. bullish engulfing (2000/2001/1990/1992 then 1992/2005/1989/2003): long at the next open 2003, stop 1989 (R 14); 1R target 2017 hit in the next bar, 2R target 2031 in the one after; all four variants take it (P below its 20-bar average, E above the 200-bar EMA)
  [ok] EG-1R: 0.9786 R
  [ok] EG-2R: 1.9786 R; the filtered variants take it too
  [ok] reference identical (4 variants)
B. bearish engulfing (2000/2008/1999/2006 then 2006/2007/1990/1995): short at 1996, stop 2007 (R 11); a later bar opens at 2010, beyond the stop: out at 2010
  [ok] gapped stop at the open: -1.3000 R; reference identical
C. no pattern: a doji before the up bar; an up bar closing exactly at the down bar's open (the close must be strictly beyond)
  [ok] no trade; reference identical
D. stop and target reached in the same minute: the stop; E. the next bar opens below the stop (1985 < 1989): no trade
  [ok] stopped at 1989
  [ok] no trade when the entry is already beyond the stop
F. the filters, after warm-up at 1900 and a jump to 2000: a bullish engulfing with P above its 20-bar average is not a reversal (EG-2R-REV skips it) but is above the 200-bar EMA (EG-2R-200 takes it); a bearish one the other way round
  [ok] filters as expected
  [ok] reference identical
G. one position at a time: a second bullish engulfing while the long is open is ignored; H. a trade still open at the end of the data closes at the last close
  [ok] one trade, the second pattern ignored
  [ok] closed at 2008 at the end of the data
