Overview

Standard Deviation (STDDEV) employs a circular buffer for O(1) streaming computation, ensuring efficient memory usage. The indicator plots the standard deviation value in a separate pane as a yellow line with a width of 2. The primary setting adjusts the lookback period, defaulting to 14, and selects the data source, which defaults to the closing price. This volatility measure helps identify periods of high and low price dispersion. It does not repaint on the live bar and provides no exit signals as it is an indicator, not a strategy.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
