MetaTrader 4 strategy testing error

 

I was doing a strategy test and it came up with the following:


2009.12.25 11:33:48 TestGenerator: unmatched data error (volume limit 120 at 2009.12.24 20:00 exceeded)


What does this mean?

 
Check your history data. Make sure it comes from the same source. Sounds like the data from various time periods are conflicting. For example, if the High for M30 happens to be higher than the High for that day etc etc. To resolve consistency issues in the history centre, you'll need to obtain a short period data set that you trust, and then generate longer period data sets from it using the period converter script.
