从零写出你自己的 MT5 EA

一门用 MQL5 编写 MT5 EA 的课程，从第一个 OnTick 讲到能自己管理风险、自己上报成绩的系统。每一课的结尾都对应一个真正在跑的 EA，代码和回测全部公开。

这门课怎么学
  • 按顺序读。每一课都建立在上一课的基础上。
  • 进入下一课之前，先把这一课的代码编译并跑一遍——只看 MQL5 学不到什么。
  • 如果某一课的结尾用到我们的 EA，它的实盘成绩和回测都在一步之内，包括没通过的那些。

    Your First EA Places No Trades

    Your first Expert Advisor should read the market and publish what it thinks — nothing more. Build the signal-only EA that fills our signals page, from its real source, and learn why every read uses the last closed bar.
