Chart pattern screener

Stocks whose price chart currently shows a known shape: a base, a double bottom or top, a breakdown, a new high or low, or an unusually quiet day. Each pattern is explained in plain English, and where we have enough history, you can see what happened after it in the past. A pattern describes the chart. It does not say what to do.

The words on this page

Trigger
The price level that completes a pattern. For an upward pattern it sits above the price, for a downward pattern below it.
Invalidation
The level at which the shape stops being that pattern. For a downward pattern it sits above the price, not below.
Shape match
How closely the price shape fits the pattern’s written definition, from 0 to 100. It is not a confidence or a probability of success.
Relative strength (RS)
How a stock’s price move ranks against every other stock we track, 1 to 99. It measures the past only.

What each state means

Every pattern moves through the same stages, whichever way it points. A state is a position in that life, not a rating.

Taking shape
The shape is starting to appear but is not complete yet.
Formed
The shape is complete and still developing. Price has not reached the trigger level.
Near trigger
The shape is complete and price is within a few percent of the trigger level.
Triggered
Price has closed past the trigger level. Nothing more than that has happened yet.
Held
Price crossed the trigger and was still past it five sessions later.
Failed
Price crossed the trigger, then came back through the invalidation level.
Broken
Price broke the invalidation level before ever reaching the trigger, so the shape no longer exists.
Finished
The pattern has run its course and is no longer active.

What this screen does not tell you

Whether a pattern will work. A detected shape is a description of past prices. The outcome figures, where shown, are what happened to earlier cases in our data, always with the number of cases behind them. They are not a forecast for any one stock.

Anything before 2020. Our usable price history starts in 2020, so a “high” is a high since then, not an all-time high.
