About MT4 EAs
MetaTrader 4 runs expert advisors written in MQL4. Many brokers still offer MT4 accounts, and a large share of the open-source EAs on GitHub were written for it. Every EA below has an .mq4 file you can read and compile in MetaEditor 4.
MT4's Strategy Tester works from one-minute history and modelled ticks, so a backtest of a scalper or a grid EA can look far better than live trading. Test on a demo account for a few weeks before you trust any result.
216 of these 840 EAs use grid or martingale logic and are marked High risk.
Before You Run One
- Copy the .mq4 file to MQL4/Experts and any .mqh files to MQL4/Include.
- Use "Every tick" modelling in the Strategy Tester, and treat M1-based results with care.
- Read the inputs: lot size, magic number and stop-loss defaults are the author's, not yours.
