ADX Trend Pullback EA: Trend Strength and Volatility-Based Trading

Brief Description

Also recommended: Trend Momentum EA - similar expert with strong performance on MetaTrader 5.

This Expert Advisor combines an ADX-based trend strength filter with an EMA pullback entry technique. It utilizes ATR for dynamic stop loss and take profit sizing and is designed for trading a single symbol with one position open at a time.

Core Strategy Concepts

The strategy is built on three established concepts:

1. Trend Strength: The Average Directional Index (ADX) measures trend strength. A rising ADX above a defined threshold indicates a developing or strengthening trend. A flat or falling ADX suggests a weak or ranging market.
2. Pullback Entry: An Exponential Moving Average (EMA) serves as a dynamic reference level. Price moving close to the EMA and then away from it is treated as a pullback within the prevailing trend.
3. Volatility-Based Risk Management: The Average True Range (ATR) expresses stop loss and take profit distances in terms of current market volatility, not fixed pip values. The Plus/Minus Directional Indicators (+DI / -DI) from the ADX indicator determine trade direction.

Signal Interpretation

All calculations are performed on closed bars of the timeframe selected in the input settings, and signals are evaluated once per new bar. The entry logic requires two conditions to be satisfied simultaneously:

1. Trend Filter: The ADX on the previous bar must be above the ADX threshold and higher than the ADX on the bar before that, indicating increasing trend strength.
2. Pullback Event: The distance between price and the EMA, expressed as a multiple of ATR, must have been at or above the pullback ratio on an earlier bar and dropped below it on the previous bar. This signifies price approaching the EMA and then moving away.

When both conditions are met, the trade direction is determined by comparing +DI and -DI on the previous bar. If +DI is greater than -DI, a buy signal is generated. If -DI is greater than +DI, a sell signal is generated. The trade direction input can restrict the EA to buy-only, sell-only, or both directions.

Stop loss distance is calculated as ATR multiplied by the SL multiplier input. Take profit distance is the stop loss distance multiplied by the risk-reward ratio input. Only one position per symbol is allowed at a time, and a new position is only considered when no position is currently open.

Suitable Symbols and Timeframes

The EA is configured by default for the H1 timeframe, but the timeframe used for indicator calculations can be changed independently of the chart timeframe through the input settings. Because the logic relies on ADX, EMA, and ATR values that adapt to current volatility, it can in principle be applied to a range of liquid symbols and timeframes. Testing on the target symbol and timeframe in the Strategy Tester is recommended before live use.
