How the play works

  1. Bullish engulfing: after a decline, a down day (close below open) is followed by an up day that opens at or below the prior close and closes at or above the prior open.
  2. Bearish engulfing: after a rise, an up day is followed by a down day that opens at or above the prior close and closes at or below the prior open.
  3. In at the close of a bullish engulfing day. Out at the close of a bearish engulfing day. Otherwise the rule keeps its last call.

A decline (or rise) means the prior close is below (or above) the close 5 sessions before it. Nison and Bulkowski require a prior trend but give no number.

Nison weighs support, resistance and confirmation, which a mechanical rule cannot judge. No confirmation day is required here.

Shadows are ignored, as both Nison and Bulkowski allow. One edge of the new body may equal the old body's edge, as in the TA-Lib pattern library, but not both.

Crypto trades around the clock, so a coin's daily open is just the prior close. For coins the open is taken as the prior close, and the pattern becomes a close beyond the prior day's open.

Where the rules come from

The case against

Valeriy Zakamulin tested moving-average timing on up to 155 years of U.S. stock data and found no statistically significant edge in the second half of that record. The rules earned their keep in a few severe bear markets and lagged buy and hold for long stretches in between.
