Expert Advisor for MetaTrader 5
1. Product Overview
Nexa BB Revert is an Expert Advisor designed around a Bollinger Bands–based mean reversion concept.
It analyzes potential short-term price retracements after periods of excessive price expansion.
The system is designed to operate on the M15 timeframe and evaluates trade conditions using a combination of Bollinger Bands, RSI, CCI, and ATR indicators.
The Expert Advisor works with a single symbol and a single position per magic number, and manages open trades automatically using predefined position management rules.
2. Trading Concept
The core logic of Nexa BB Revert is based on the following conditions:
-
Price reaches the upper or lower Bollinger Band
-
Price returns back inside the band on the following candle
-
RSI and CCI indicate overbought or oversold conditions with directional change
Trades are considered only when all required conditions are met simultaneously.
Optional filters, such as ATR range and ADX strength filters, can be enabled to avoid trading during periods of excessive volatility or strong directional trends.
