mql4 - MetaTrader 终端 4：根据历史数据调试智能交易系统

问题描述

我有一个 MetaTrader 终端 4 登录到一个模拟账户。

我编写并编译了我的第一个智能交易系统。

我可以在实时图表上调试它，所以工作正常。我想在历史数据上调试它。在 MetaEditor 中，历史数据上的调试>开始是灰色的。

此外，在运行策略测试器时，我的断点永远不会被击中，我将断点放在OnTick()函数的第一行，所以在我的理解中它应该会被击中。

这是因为我有一个模拟账户吗？如果不是，我如何根据历史数据调试我的脚本？

下面更新代码

解决方案

问：“这是因为我有一个模拟账户吗？”

不。

问：“如果不是，我如何根据历史数据调试我的脚本？”

在 MT4 (as-is-2020/06)中，如果需要，您仍然可以实施您自己的“调试”-Inspector/Monitor-agent 工具，以便在StrategyTesterMQL4 运行模式期间执行编译-EA。

MT4StrategyTester是一种回溯测试工具，而不是（模拟的）实时市场模拟器和调试器，它仅在合成（加速|减速）时间内运行 EA，使用受控的合成QUOTE消息流)，针对给定的交易工具和时间框架进行模拟。
