今天在测试EA时，打开自动调整网格间距函数功能时，报上述错误，而不使用该功能时，则正常出结果，从google搜索了一下，发现以下结果，

This has nothing to do with lot size or the strategy. It's the same as all 'unmatched data errors', only in this case the volume is unmatched (usually O/C/H/L are unmatched). It means the tester is using data from a lower timeframe to test the EA on a larger timeframe, but the volume in the larger timeframe is not the sum of volumes of the lower timeframes... Hence - unmatched data error - this is literally the problem.

To solve this problem, build all larger timeframes from M1 data using the standard period_converter script. Please search for more info (this error and it's solution have been discussed many times).

       意思是说，没关系，M1数据源不足。

       我检查了一下，我的这个功能函数需要计算前20天的D1数据，而测试的AUDUSD恰好日线数据不足，另外洋人说不影响EA策略，那我就放心了。
