MQL5 Swing Trading EA: Code, Multi-Day Hold Logic & Backtest
This page provides a complete MQL5 Expert Advisor for swing trading across multiple currency pairs, holding positions for multiple days to capture medium-term trend moves. It covers the full EA source code, entry and exit logic based on moving average crossovers and ATR-based stops, plus backtest results from 2020–2025.
Historical test results
Past performance is not indicative of future results. Backtest statistics are based on historical data and do not guarantee future profits. Trading involves significant risk of loss. This content is for educational purposes only and does not constitute financial advice.
Strategy logic
Entry conditions
A long entry is triggered when the 20-period EMA crosses above the 50-period EMA on the H4 chart, confirmed by RSI(14) above 50 to filter out weak momentum setups. A short entry fires when the 20 EMA crosses below the 50 EMA with RSI below 50. To avoid entering during high-volatility news events, the EA checks that the spread is within an acceptable multiple of the average ATR before placing any order.
Exit conditions
Each trade is protected by an initial stop loss placed 1.5 x ATR(14) beyond the entry candle high or low, providing volatility-adjusted risk control. A trailing stop activates once the trade moves 1 x ATR in profit, locking in gains as the swing progresses over multiple sessions. The EA also closes a position if the EMA crossover reverses, signalling that the medium-term momentum has shifted.

Pine Script vs MQL5: Same Strategy, Different Platforms
| Aspect | Pine Script (TradingView) | MQL5 (MetaTrader 5) |
|---|---|---|
| Execution | Series evaluated on chart updates | Event handlers with explicit buffers |
| Deployment | Runs in TradingView with alerts | Runs in the MT5 terminal or on a VPS |
| Broker access | Via TradingView broker integration | Direct broker connectivity |
| Backtesting | Strategy Tester for strategy scripts | Strategy Tester for Expert Advisors |
| Code complexity | Simpler, functional syntax | C++-like, more powerful |
The calculation can be implemented on either platform, but the runtime model and buffer APIs differ. Read the Pine Script Supertrend reference before porting logic between them.
