Key Reversal Patterns: Engulfing, Pin Bar, and Inside Bar

Three candlestick patterns account for the majority of high-probability price action setups used by professional traders.

The Engulfing Pattern

A bullish engulfing pattern occurs when a bearish candle is followed by a bullish candle whose body completely contains (engulfs) the prior bearish candle's body. The implication: sellers were in control, but buyers overpowered them so decisively that they reversed the entire prior move and then some.

The pattern is most powerful when it occurs at a key support level after a downtrend. A bearish engulfing at resistance after an uptrend carries equivalent bearish significance.

The Pin Bar (Pinbar)

A pin bar has a small body and a long wick in the direction of the rejection. The wick should be at least twice the length of the body, and the body should close at or near the opposite end of the candle.

A bullish pin bar at support says: price was aggressively pushed down into the support zone, buyers rejected the move, and price closed back above the open near the high of the candle. This is one of the cleanest expressions of institutional buying interest at a key level.

The Inside Bar

An inside bar is a candle whose high and low are both within the range of the prior candle (the "mother bar"). It represents compression — a pause as market participants wait for new information. An inside bar after a strong impulse move often signals continuation, as the pause is corrective rather than reversal.

A break of the inside bar's high (after a bullish impulse) or low (after a bearish impulse) is a valid entry trigger for experienced traders who want a precise entry point.

The Most Important Rule

None of these patterns are entries on their own. They are confluence signals. A pin bar at random price is noise. A pin bar at key support, in the direction of the higher timeframe trend, after a corrective pullback — that is a signal. Learn to stack confluence before you pull the trigger.

Key Takeaways

✓ A 70% win rate strategy can lose money. A 40% win rate strategy can make money. Win rate alone is meaningless.
✓ Expectancy = (Win Rate × Avg Win) – (Loss Rate × Avg Loss). Calculate this before trading any strategy.
✓ Positive expectancy over a large sample is the only real definition of a working strategy.
✓ Never judge a strategy on fewer than 50 trades — that is not enough data to separate edge from variance.
