What is a Bull Trap?
A bull trap is a false signal that makes it look like a stock is breaking out above resistance, encouraging traders to buy. Shortly after the breakout, the price reverses and drops back below the resistance level, trapping the buyers who entered on the break.
How a bull trap works
- A stock approaches a well-known resistance level (previous high, round number, or moving average).
- Price breaks above resistance. Breakout traders enter long. Stop-buy orders trigger.
- The move stalls. Volume does not confirm. Early sellers start hitting the bid.
- Price drops back below resistance. The buyers who entered on the break are now underwater.
- Stop losses trigger, adding selling pressure. The stock falls further.
How to avoid bull traps
- Wait for confirmation: do not buy the first candle above resistance. Wait for a close above the level, or better yet, wait for a pullback to the breakout level that holds as new support.
- Check volume: a real breakout comes with above-average volume. If RVOL is below 1.0 on the break, be skeptical.
- Watch the time of day: breakouts during the midday lull fail more often than breakouts during the opening drive or power hour.
- Use a stop loss: if you trade the breakout and it fails, your stop below the resistance level limits the damage. Proper position sizing makes a failed breakout a small loss, not a disaster.
Bear trap
A bear trap is the opposite: a false breakdown below support that traps short sellers. The price breaks below support, shorts enter, then the stock reverses sharply upward. Same concept, opposite direction.
