Double Top vs. Double Bottom: Entry, Stop, and Target Rules
The double top and double bottom are the "M" and "W" of trading — the reversal patterns you'll see more than any other. They're simple to spot and, when traded with a plan, offer a clean entry, an obvious stop, and a built-in target.
A double top forms after an uptrend: price pushes to a high, pulls back, then rallies to roughly the same high — and fails. Two peaks at similar levels, like the letter M. It signals buyers tried twice to break higher and couldn't. A double bottom is the mirror image after a downtrend: two lows at a similar level, like a W, signalling sellers couldn't push lower.
The neckline is the trigger
Here's the rule beginners skip: two peaks alone are not a double top. The pattern isn't confirmed until price breaks the neckline — the low of the pullback between the two peaks. Until that break, you just have price bouncing in a range, and it could push to new highs at any moment.
Shorting the second peak because "it looks like a double top" is anticipation, and it's how traders get caught when the pattern never completes. Wait for the neckline to break with a decisive close. For a double bottom, it's the reverse: wait for price to break above the neckline (the high between the two lows) before going long.
The full trade plan
Entry
On a confirmed close beyond the neckline — below it for a double top, above it for a double bottom. Some traders wait for a retest of the neckline for a tighter, lower-risk entry.
Stop loss
Beyond the pattern's extreme: above the two peaks for a double top, below the two lows for a double bottom. If price returns past that level, the reversal has failed and there's no reason to stay in.
Target (measured move)
Measure the height of the pattern — from the peaks down to the neckline — and project that same distance from the neckline break. That projection is your objective target, calculated before you enter rather than guessed at afterward.
The best double tops/bottoms have two peaks (or lows) at genuinely similar levels, a clear pullback between them, and ideally lower volume on the second push — a sign the move is running out of fuel.
Common mistakes to avoid
- Trading it against a strong trend with no other confluence — reversals against a powerful trend fail more often.
- Entering before the neckline breaks — the single most common way to lose on this pattern.
- Forcing the pattern when the two peaks are at very different heights — that's not a clean double top.
- Ignoring the measured target and holding "for more," giving back profits when price reverses again.
Key takeaways
- Double top (M) = two failed highs, a bearish reversal; double bottom (W) = two failed lows, bullish.
- Not confirmed until the neckline breaks — never anticipate.
- Stop beyond the peaks/lows; target = pattern height projected from the neckline.
- Best with similar-level peaks, a clear middle pullback, and fading volume on the second push.
