提示手数无效，你代码中要对品种的最小手数，最大手数做个验证。

您好！ 我还是不太明白 “验证” ，能具体些么 。 还有 Invalid stops这个错误 也是需要验证？

除此之外，还需要验证当前账号资金是否够开仓等等，具体阅读这篇文章：

你好 不知道我哪理解不对。 我对SYMBOL_TRADE_STOPS_LEVEL 验证的代码修改如上一条评论，还是会Invalid stops。 注意到都是在 Modification failed之后，我对SYMBOL_TRADE_FREEZE_LEVEL的验证又做了 如下一条评论。
//在更改挂单 止盈 止损的函数中，增加了SYMBOL_TRADE_FREEZE_LEVEL的现在

可以试试把单量规范一下！
您好！单量更改没问题了 stop_level 和freeze_level的更改你觉得还差什么？ 谢谢
我在MT5上测试是没有这样的问题，怎么解决呀？谢谢！
