EA AUTOMATED TRADING · MT4/MT5
Learn MT4/MT5 automated trading from scratch — MQL4/MQL5 programming, EA strategy development, backtesting, and live deployment. Curated free tools and strategy templates.
⚠️ HIGH RISK WARNING
EA automated trading involves significant financial risk. FX and CFDs are leveraged products that can result in total loss of capital. Grid and Martingale strategies are especially dangerous — trending markets can blow up accounts. All content is for educational purposes only, not investment advice. Only trade with money you can afford to lose completely.

The classic EA entry strategy. Open long when short MA crosses above long MA, short when below. Simple and intuitive, perfect for understanding EA basics. Built-in MT4/MT5 indicators, ~20 lines of MQL code.
Place equidistant orders in a preset price range — take profit and place reverse orders on price moves, continuously profiting in ranging markets. Set total exposure cap and max loss limit to prevent blow-up in trending markets.
Double position size after losses to average down — high win rate but extreme risk. Correct usage: limit layers (max 3-4), run only in low volatility, set hard stop-loss. Never unlimited doubling — fastest path to account destruction.
Use ADX/Bollinger/Channel breakout to determine trend direction, trade with the trend, lock profits with trailing stops. Steady annual returns but requires patience — consecutive stop-outs in ranging markets. Key: strict stop-loss discipline and position sizing.
Cross-symbol/cross-broker hedging — long and short highly correlated instruments to profit from spreads. Triangular arbitrage exploits pricing discrepancies among 3 currency pairs. Requires ultra-low latency and multiple broker accounts — high barrier for retail traders.
❌ Trap: 市场上99%的「月收益30%，回撤<5%」的EA都是过度优化的结果（曲线拟合），在样本外数据上立刻失效。任何承诺无风险高收益的EA都是骗局。
✅ Fix: 要求看至少2年以上的真实交易记录（Myfxbook已验证或Darwinex公开数据），而非回测报告。对所有EA保持怀疑——如果它真的那么赚钱，为什么还要卖给你？
❌ Trap: 很多EA（尤其是网格和马丁）不设止损或止损极宽。遇到极端行情（如瑞郎黑天鹅、英国脱欧）时，一次亏损就能抹去数月的盈利甚至爆仓。
✅ Fix: 自己修改EA源码加上硬止损——每单最大亏损不超过账户的2%，每日最大亏损不超过5%。不要完全信任EA的风控——自己做最后一道防线。
❌ Trap: 在回测中反复调整参数直到收益率曲线完美无瑕——这是典型的过拟合。参数越多、回测次数越多，样本外失效的概率越高。
✅ Fix: 用Walk-Forward分析替代简单调参。在训练集上优化、验证集上测试、样本外确认——三段式验证。参数量控制在3-5个以内。
❌ Trap: 回测中不设点差和手续费，高频EA看起来极其赚钱——加上2-3点的真实点差和每手佣金后，90%的高频策略从盈利变亏损。
✅ Fix: 回测中设置大于正常水平的点差（如EURUSD至少2点）、加上佣金（每手7-10美元）、考虑滑点（市价单2-3点）。如果这些成本下仍盈利，策略才可能真实可行。
❌ Trap: 重大新闻（非农、利率决议、CPI）发布时市场波动剧烈，EA的止盈止损可能被击穿，滑点巨大。很多EA的「最大回撤」记录都是被一次非农之夜打破的。
✅ Fix: 在EA中加入时间过滤器——重大新闻发布前15分钟到后30分钟暂停交易。用经济日历API（如ForexFactory Calendar）自动检测新闻事件，提前平仓或暂停开仓。
❌ Trap: 只跑一个EA在一个品种上——当这个策略在这个品种上失效时（所有策略都会失效），没有其他盈利来源弥补亏损。
✅ Fix: 至少跑3-5个不同风格的EA（趋势、震荡、套利各一个），分散在3个以上的不相关品种上。建立策略组合，定期评估整体夏普比率和相关性，而非关注单一EA的盈亏。
