Master Head and Shoulders, Double Top and Double Bottom

The head-and-shoulders pattern is a reversal setup built from three peaks. A left shoulder forms first, then a higher head in the middle, then a right shoulder that comes back down to roughly the same height as the left shoulder. Connect the two low points between those peaks and you get the "neckline" -- when price breaks convincingly below it, that's the signal an uptrend has flipped into a downtrend.

Flip the whole shape upside down and you get the inverse head-and-shoulders: three troughs, with a lower head in the middle, and a neckline drawn across the two highs between them. A confirmed break above that neckline signals the opposite reversal, from a downtrend into an uptrend.

Double tops and double bottoms are a simpler version of the same idea. Instead of three peaks you get two peaks at roughly matching heights (or two troughs for a double bottom), and a break of the level between them is read as the same kind of reversal signal.

The value here has nothing to do with the shape looking neat on a chart. It's about what the shape reveals about who's in control. A right shoulder that fails to exceed the head is a visible sign that buying pressure is already fading. When the neckline breaks on top of that, it confirms sellers have taken over a level that used to be support.

This is the exact same crowd-psychology mechanism behind support and resistance role reversal, just spread out across three swings instead of one flat line. The pattern is really just a slow-motion picture of buyers losing control.

The most common mistake is calling a setup a head-and-shoulders while the right shoulder is still forming. Nothing is confirmed until the neckline actually breaks. Plenty of setups that "look like" a head-and-shoulders never break the neckline at all, and the supposed head just turns into another new high in a trend that keeps going.

Two things matter for real confirmation. First, watch for rising volume on the neckline break itself -- a break that barely pokes through on thin volume is much more likely to be a fakeout. Second, consider waiting for a retest, where price comes back to the broken neckline and gets rejected by it as new resistance. Acting on the retest is a more conservative, higher-confidence entry than reacting the instant the neckline first breaks.

Enter on the confirmed neckline break, or on the retest if you want a more conservative entry. Place your stop just above the right shoulder's high -- for the reversal thesis to still hold, price should not be able to climb back above that level.

For the target, use the standard measured-move technique: measure the vertical distance from the top of the head down to the neckline, then project that same distance downward starting from the breakout point.

A pattern that gets forced onto charts constantly is calling any three bumps a head-and-shoulders, even when the shoulders are wildly uneven in height or the whole thing is really just normal choppy price action with no clean structure.

The pattern only has predictive value when the shoulders are reasonably close in height and the neckline break is decisive, not squinted into existence after the fact. If you have to convince yourself it's there, it probably isn't.

Neither head-and-shoulders nor double top/bottom will predict the future perfectly, but the neckline gives you an objective line to plan an entry and a stop around instead of guessing.

Once the pattern has handed you an entry and a stop-loss level, the last step is sizing the position correctly around that gap.
