Syntax

Syntax
ta.stoch(source, high, low, length) → series float

Arguments

ParameterTypeDescription
sourceseries int/floatSeries compared to the range (commonly close).
highseries int/floatHigh series for the range calculation.
lowseries int/floatLow series for the range calculation.
lengthseries intLookback length for highest/lowest range.

Returns

Stochastic.

Remarks

na source values are ignored. A zero high-low range makes the ratio undefined. The usual 0–100 interpretation assumes the source lies within the supplied range; arbitrary input series need not do so.

Code Examples

Frequently Asked Questions

ta.stoch() returns the raw stochastic %K-style value for the chosen source within the high/low range over length bars, scaled to 0–100.

Call ta.stoch(close, high, low, kLength) for raw %K. For a slow stochastic, smooth raw %K first, then smooth that result for %D. Specify both smoothing lengths and methods; ta.stoch() alone does not return a %K/%D tuple.

Common defaults are about 80/20 or 70/30, but no threshold is universally optimal. Treat them as context, not automatic trade triggers.
