Execution errors：http://docs.mql4.com/trading/errors

MetaEditor没有debug功能，不能设断点，发生错误的时候完全不知道自己错在哪里。

运行EA的时候，出现了error代码也不知道是什么意思。

以上三个网页基本可以解决这些问题。

以后出麻烦了就来看看。

1. syntax – they can be found at the compilation stage and can be easily fixed by the programmer;
2. logical – they are not detected with a compiler. The examples are: a mess with the names of the variables, the wrong function calls, operation of the data of various types and so on;
3. algorithmical – they occur when the brackets are not placed correctly, in case of a mess with the branch statements and so on;
4. critical – these are improbable errors, you should spend some effort to evoke them. Non the less they often occur when you work with dll;
5. trading – these are the errors that occur when you work with the orders. Such kind of errors is a tender spot for trade robots.

这行业的确都在藏着掩着，根本找不到人跟你切磋代码这种表层的东西，更不用想去找人跟你讨论十分实质的东西。以下是我做的第一个EA。对这个处女作我非常满意。
复盘模型质量90%。两年资金翻三倍。这个EA还是有些硬伤，这几天把它optimizer一下。测试EA十分能耗硬盘啊。我的D盘宝贝又被我删了10G.....
