Bulkowski rank (bullish)
// key takeaways
▸ Three troughs at a similar low with two peaks between them.
▸ The resistance across the peaks is the confirmation line.
▸ Confirmation is a close above that resistance — a firm base breaking out.
▸ Target = pattern height projected up from the breakout.

Triple bottom — three equal lows, confirmed on the resistance break.
How it forms
Price tests the same support level three times and holds each time, carving out a broad, sturdy base. Each failed break lower drains selling pressure. The horizontal line across the two interior peaks is the resistance; a close above it confirms the bullish reversal.
The trading playbook
› Entry — on a close above the peak resistance, or on the throwback that retests it as new support.
› Stop — below the triple-bottom lows.
› Target — measure from the lows to the resistance and project that height above the breakout.
Why it is dependable
Three successful defences of a level is stronger evidence of a base than one or two. Bulkowski's sample shows a low ~13% failure rate and a ~74% target-hit rate — but the pattern still only pays once resistance breaks, so patience beats anticipation.
// common mistakes
✕ Buying the third bottom before resistance breaks.
✕ Requiring the three lows to be identical — close is enough.
✕ Ignoring volume, which should expand on the breakout.
