Chart pattern explorer

All 16 patterns in the GMR library. Every one lists its completion condition and its invalidation, because a pattern with no stated way to be wrong is a prediction, not an observation.

Level

Support zone

Bias: contextual

Needs: multiple reactions or a clear prior pivot
Confirmation: hold/rejection or reclaim
Invalidation: decisive close below with follow-through
Common mistake: drawing an exact one-pixel line instead of a zone

Resistance zone

Bias: contextual

Needs: multiple reactions or a clear prior pivot
Confirmation: rejection or breakout+hold
Invalidation: clean acceptance above
Common mistake: assuming every first touch reverses

Compression

Ascending triangle

Bias: often bullish, not guaranteed

Needs: flat resistance; rising swing lows
Confirmation: close above resistance; acceptance/retest
Invalidation: break below rising support
Common mistake: calling it before price leaves the structure

Descending triangle

Bias: often bearish, not guaranteed

Needs: flat support; falling swing highs
Confirmation: close below support; acceptance/retest
Invalidation: break above falling resistance
