Bollinger BandWidth Percent for NinjaTrader
Rating:

Tags:
bands, ninjatrader
Bollinger Percent (%), like Bollinger Bandwidth, is based on the Bollinger Bands indicator, which was developed by John Bollinger. The Bollinger Bands indicator was developed to measure a stock’s volatility. Furthermore, both Bollinger Bandwidth and Bollinger Percent are used in technical analysis for the same purpose of volatility evaluation.
