Source Code

Overview
Alpy VIX computes standard deviation bands and percentile boundaries over customizable lookback periods, coloring histogram bars when volatility reaches extreme levels. Strategy execution settings allow massive pyramiding and recalculation on every tick, which can cause intrabar repainting, and the visible script includes no stop loss or take profit mechanisms.

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.
