Bullish engulfing pattern: does it work?
A bullish engulfing pattern is a green candle whose body completely covers the previous red candle’s body, after a fall. In one day, buyers took back everything sellers won the day before.
When “Bullish engulfing” appeared, NIFTY 200 stocks were higher 12 trading days later 54.3% of the time, against 55.3% after any day: about the same as picking a random day.

What it is
A bullish engulfing pattern is a green candle whose body completely covers the previous red candle’s body, after a fall. In one day, buyers took back everything sellers won the day before.
How we detected it
A red candle is followed by a green one that opens at or below the red close and closes at or above the red open, with a body more than 1.05 times the red body. Only bodies are compared, not wicks. Before the red candle, the close fell more than 2.5% over the 8 days before it. We count the green day.
How traders read it
It is a sign that the balance has flipped, not a guarantee the fall is over. Traders give it more weight at support or on heavy volume, and many wait for a follow-through close higher.
A signal is a probability, not a promise
Even the most reliable signal in this study was followed by the opposite move 37% of the time. A signal tilts the odds; it doesn’t decide the outcome.
Signals work better when they agree with the trend and with each other. Whatever the signal, decide your stop-loss before you act.

How these numbers were made
We ran the same signal detector MarketSeekho uses to grade players over every trading day of 187 NIFTY 200 stocks, Jan 2021 to Oct 2025, using NSE end-of-day prices (1,54,833 stock-days). We counted the first day a signal appeared, then ignored the same signal on the same stock for 12 trading days so results don’t overlap. Windows with splits, bonuses or trading halts were left out.
“Any day” is the baseline: the same measure after every day in the data, signal or not. It matters because 2021–2025 was mostly a rising market, so stocks were higher after 12 days more often than not anyway. Past results don’t predict future ones, and this is not investment advice.
