By Islam BarakaDefinitions
In plain terms
The bullish neckline can slope rather than remain horizontal.
Technical
N_t = n1 + (n2-n1)/(i2-i1) × (t-i1) using confirmed peak indexes and prices.
Scope
The projected line describes the detector boundary and is not a guaranteed resistance level.
Formula
N_t=n1+(n2-n1)/(i2-i1)*(t-i1)N_t=n_1+\frac{n_2-n_1}{i_2-i_1}(t-i_1)| Symbol | Meaning | Unit |
|---|---|---|
n1,n2 | peak anchor prices | price |
Output unit: price
Examples
- A reviewer computes Triple Bottom Neckline Projection on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.
Common misconceptions
- The projected line describes the detector boundary and is not a guaranteed resistance level.

Evidence and governance
- Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation Lo, Mamaysky, and Wang · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: The paper's smoothing, sample, and empirical design are not copied into this package and do not validate its thresholds.
- Pine Script repainting concepts TradingView · official platform documentation
Supports: preferred label, short definition, technical definition, formula
Limits: Platform display behavior does not establish financial usefulness or predictive value.
- scipy.signal.find_peaks SciPy · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: This retrospective signal function is not itself a causal OHLC pivot detector.
- Pine Script pivot techniques TradingView · official platform documentation
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.
