Updates since the last close

Every night we scan the market for stocks building a base and stocks breaking out of one. This page lists only what changed since the scan before: which stocks broke out, which started a new base, and which slipped back below the price they had cleared.

Changes by kind

What each kind of change means

Broke out
Closed above the top of its base (the trigger price) since the last scan.
New base
Started building a new base: trading sideways in a range after a rise.
Fell back
Had broken out, then closed back below the trigger price, so that breakout did not hold.
Moved stage
Moved to a different stage, for example a recent breakout that has now held for more than five sessions.
Base ended
Was in a base or a breakout, and the scan no longer recognises a base on its chart.
Left the scan
Dropped out of the stocks we scan, usually because too little of it traded recently.

What this page does not tell you

A change is a description of what price did between two scans, not a forecast. A breakout can fall back within days, and a new base can fail without ever breaking out. Nothing here carries a chance of success, because none has been measured.

Prices are end-of-day. If a night’s scan did not run, the next one is compared with the last scan that did, so a single update can cover more than one trading day.

The list starts on the day this feature went live. Earlier days cannot be added afterwards: the scan keeps only where each stock stands today, so the comparison has to be recorded on the night it happens.

Base and breakout detection describes past price and volume. It is provided for research and education, is not investment advice, and no pattern or threshold predicts future returns.
