Overview
Mean Reversion Scalper is a fully automated trading robot designed for the MetaTrader 5 platform. As the name suggests, this Expert Advisor operates on the mean reversion principle, identifying overextended price movements and capitalizing on the market's natural tendency to return to its average.
The core logic is built around the Bollinger Bands indicator, one of the most popular and effective tools for identifying overbought and oversold conditions in the forex market. Additionally, the EA incorporates the ADX (Average Directional Index) indicator to confirm sideways or ranging market conditions, helping to avoid false signals. The RSI (Relative Strength Index) is also used to pinpoint overbought and oversold zones. The EA essentially looks for confluence among all these indicators to generate high-probability entry signals.
This EA is now fully developed and ready for live market use. It is no longer in a testing phase — all core logic, risk management, and execution modules have been completed and refined.
How It Works
The EA monitors price action relative to the Bollinger Bands and executes trades when price extends beyond the bands, anticipating a reversal back toward the middle band (the moving average). The ADX indicator is used as a confirmation filter — trades are only considered when the ADX value is below a certain threshold, indicating a sideways or non-trending market, which is the ideal environment for mean reversion strategies. The RSI further refines entries by ensuring that price is in overbought (for sell signals) or oversold (for buy signals) territory. The EA only takes a trade when all three indicators align, providing a confluence of signals that increases the reliability of each entry.
Key concepts used in this EA:
| Concept | Description |
|---|---|
| Mean Reversion | The idea that price tends to return to its average over time. When price moves too far from the mean (either up or down), the EA expects a pullback. |
| Bollinger Bands | A volatility indicator consisting of a middle band (SMA) and two outer bands (standard deviations). The EA uses these bands to identify entry and exit points. |
| ADX Indicator | Used to confirm sideways or ranging market conditions. The EA only enters trades when the ADX is low, indicating a lack of strong trend, which increases the probability of a mean reversion. |
| RSI (Relative Strength Index) | Used to identify overbought and oversold zones. The EA looks for RSI values above 70 (overbought) for sell signals and below 30 (oversold) for buy signals. |
| Confluence of Indicators | The EA requires alignment of Bollinger Bands, ADX, and RSI before entering a trade, ensuring higher confidence and filtering out weak or false signals. |
| Scalping | The EA aims to capture small, quick profits from short-term price movements, making it suitable for active trading sessions. |
Risk Management Modes
The EA now includes three selectable risk modes, allowing you to choose the position sizing method that best fits your trading style and account size:
| Risk Mode | Description |
|---|---|
| Fixed Percentage of Equity | Each trade risks a fixed percentage of your account equity. The lot size is calculated automatically based on your stop loss distance and the specified risk percentage. |
| Fixed Lot Size | Each trade uses a fixed lot size that you define manually. Simple and straightforward for traders who prefer consistent position sizing. |
| Fixed Dollar Amount | Each trade risks a fixed dollar amount. The EA calculates the appropriate lot size so that if the stop loss is hit, the loss does not exceed the specified dollar value. |
You can switch between these modes easily from the EA settings, giving you full control over your risk exposure in different market conditions.
Settings & Parameters
The EA comes with a clean, user-friendly interface with essential parameters exposed for easy customization.
