Description

This expert advisor automates a Bollinger Bands trading strategy with full flexibility. The EA can trade in four different behavioral modes: Regular (selling when price exceeds the upper band and buying when it drops below the lower band), Inverse (buying above the upper band and selling below the lower), Only Buy (trading only long when price is below the lower band), and Only Sell (trading only short when price is above the upper band). These options allow you to fine-tune your trading logic to match your market bias.

It also supports four money management modes: fixed lot size, dynamic risk as a percentage of account equity, martingale (doubling after a loss), and inverse martingale (doubling after a win). You can also filter trades by forex session (Asian, European, American) and activate multi-timeframe confirmation, where the EA checks for price to be in an overbought or oversold condition across several timeframes before entering a trade.

Trades can be managed with built-in breakeven, trailing-stop, and traditional SL/TP mechanisms. You can even choose to exit trades when the price reverts to the Bollinger Bands midline, simulating mean reversion logic.

Input Parameters

  • Trading Settings: Choose trading direction (regular, inverse, only long, only short) and whether to trade at bar close only or intra-bar with tick execution.
  • Bollinger Bands: Set the period and deviation for the Bollinger Bands indicator.
  • Timeframe Filters: Select multiple timeframes to confirm overbought or oversold conditions for multi-timeframe validation.

  • Money Management: Set a fixed lot size or allow the EA to auto-calculate it. Enable martingale or inverse martingale logic.
  • EA Settings: Set the magic number, custom trade comment, and manual pip value override. Only modify advanced settings if you understand their function.

Frequently Asked Questions

The EA uses the Bollinger Bands indicator to determine entry points. Depending on the selected trading behavior, it will buy below the lower band, sell above the upper band, or perform inverse or one-sided logic. You can also enable confirmation from multiple timeframes to enhance signal quality.

Yes, the EA is compatible with ECN and non-ECN brokers and supports symbols with 2, 3, 4, or 5 digits. It is also fully NFA/FIFO compliant, which means it can be used under U.S. regulatory conditions.

Multi-timeframe filtering allows you to require the Bollinger Bands signal to be valid across several timeframes before taking a trade. For example, you can set it to only trade when the price is oversold on M15, M30, and H1 simultaneously. This helps reduce false signals and improve trade timing.

Regular behavior sells above the upper band and buys below the lower band, following the logic of price mean reversion. Inverse behavior flips this logic and is used when traders believe a breakout will continue in the same direction rather than revert to the mean.

The EA includes full control over position management: set fixed or dynamic stop-loss and take-profit, apply break-even rules, trailing-stops in percent or pips, and define whether to close trades when the price returns to the Bollinger Bands average. It also offers money management modes such as fixed lot, percentage risk, martingale, and inverse martingale.

Yes, the EA is fully compatible with the MetaTrader strategy tester. You should use it to explore the best-performing parameters and timeframes for your preferred instruments. The EA’s flexibility makes it important to configure settings carefully to match the market’s behavior.

This is up to you. You can configure the EA to only trade at the closing of a candle (more conservative and stable), or to execute trades in real-time during candle formation based on tick data (more responsive, but also riskier).

It depends on your settings. If the price is not reaching the Bollinger Bands levels defined by your strategy and timeframe, the EA will not place trades. You may need to adjust band periods, trading frequency, or volatility conditions for quieter markets.

Yes, once a trade is open, the EA can manage it automatically according to your break-even, trailing-stop, SL/TP, or exit-on-midline settings. It will also skip entry signals if existing trades are still running unless otherwise specified.
