By Islam BarakaDefinitions
In plain terms
It extends a double bottom with a third comparable test and a projected neckline through the two peak anchors.
Technical
The selected close-only contract requires a low-high-low-high-low sequence, three-way similarity, retracements, prior decline, and a later strict upside break.
Scope
Three support visits do not confirm a reversal until the causal neckline rule passes.
Formula
three comparable lows, two peaks, projected neckline, then strict upside breakL-H-L-H-L,\quad C_t>N_t| Symbol | Meaning | Unit |
|---|---|---|
N_t | projected neckline | price |
Output unit: pattern state
Examples
- A reviewer computes Triple Bottom on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.
Common misconceptions
- Three support visits do not confirm a reversal until the causal neckline rule passes.

Supports: preferred label, short definition, technical definition, formula
Limits: This retrospective signal function is not itself a causal OHLC pivot detector.

Supports: preferred label, short definition, technical definition, formula
Limits: The package freezes its own equality, separation, and OHLC policies rather than claiming one universal pivot definition.
