A Bollinger Bands Mean-Reversion Trading Expert Advisor

Summary

This document describes an expert advisor that trades around Bollinger Bands. Its stated rule is contrarian: a downward break below the lower band triggers a buy, while a break above the upper band triggers a sell. An update says entries are placed after a bearish or bullish candle, respectively, and notes small issues with closing positions after a specified time.

The configurable controls cover position sizing, fixed or percentage-based volume, stop-loss distance, session start and end timing, indicator-based exits, trailing stops, breakeven handling, risk-reward settings, and closing losing positions after a time limit. The description does not provide entry filters beyond the band break and candle condition, nor does it explain parameter values, markets, timeframes, transaction costs, or performance evidence. It recommends trying the system in a backtester or demo account, so the document should be treated as a basic strategy description rather than evidence of profitability.

Key ideas

• The EA buys after price breaks below the lower Bollinger Band and sells after an upper-band break.
• An update specifies waiting for a bearish or bullish candle before opening the corresponding position.
• Settings include volume and risk controls, session timing, and several stop and exit options.
• The document reports minor time-based closing issues and provides no backtest results or detailed market specification.
