Bilateral patterns

Broadening formation

No built-in bias

Higher highs and lower lows — a range that expands rather than contracts.

What a broadening formation tells you

Expanding volatility with no agreement on value. It is one of the hardest environments to trade and is often best left alone, which is a legitimate conclusion.

Why it forms

Emotional, headline-driven participation; each swing overshoots the last.

How traders enter it

Some traders fade the extremes; breakout entries are unreliable because there is no compression to release.

How it fails

Stops must be wide, so position sizing gets small; the pattern chews up traders who size for a normal range.

That last section is the one worth rereading. A pattern is only useful because it comes with a level that proves you wrong — without one you have a shape and a hope.

When does a broadening formation fail?

Stops must be wide, so position sizing gets small; the pattern chews up traders who size for a normal range.

Can ChartLens spot a broadening formation for me?

Yes. Photograph or screenshot any chart and ChartLens names the pattern if it is clearly formed, with a confidence level and whether it is forming, confirmed or failed — and says nothing if it is not there.
