BB-RSI-ADX Entry Points

This is a combination of indicators used to find oversold and overbought entry points for possible reversion.

A Green arrow will appear when all condition are met for an ENTER LONG position. A Red arow will appear when all condition are met for an ENTER SHORT position.

You can modify all of these condition parameters from the indicator’s settings.

How does the indicator work The signals are using Bollinger Bands, BB %B, RSI and ADX indicators to try and find points of reversal

Enter LONG Conditions Current candle low is below BB lower band. The BB %B is more than 0. RSI > 30 ADX > 25

Enter SHORT Conditions Current candle high is above BB upper band. The BB %B is less than 1. RSI < 70 ADX > 25

Those are the default settings that seem to work for me but you can customize all of these from the indicator settings. I find this strategy to best work on a 3 minute timeframe

Note: The bb %B is calculated for stDev - 1. This will help you see a change happening faster.
