I've used Birt’s CSV2FXT script v0.50 to convert CSV data for 2014 into FXT, however it's showing the errors as shown below when testing on M30 timeframe (any EA):
TestGenerator: spread set to 10
TestGenerator: unmatched data error (volume limit 385 at 2014.01.06 05:30 exceeded)
TestGenerator: unmatched data error (volume limit 239 at 2014.01.07 04:30 exceeded)
TestGenerator: unmatched data error (volume limit 368 at 2014.01.07 22:00 exceeded)
TestGenerator: unmatched data error (volume limit 732 at 2014.01.08 11:30 exceeded)
TestGenerator: unmatched data error (volume limit 197 at 2014.01.08 22:00 exceeded)
TestGenerator: unmatched data error (volume limit 251 at 2014.01.10 03:30 exceeded)
TestGenerator: unmatched data error (volume limit 412 at 2014.01.10 05:00 exceeded)
TestGenerator: unmatched data error (volume limit 239 at 2014.01.10 05:30 exceeded)
...
TestGenerator: unmatched data error (volume limit 149 at 2014.02.24 22:00 exceeded)
TestGenerator: unmatched data error (volume limit 357 at 2014.02.25 00:00 exceeded)
TestGenerator: unmatched data error (volume limit 301 at 2014.02.25 02:00 exceeded)
TestGenerator: unmatched data error (volume limit 179 at 2014.02.25 05:00 exceeded)
TestGenerator: unmatched data error (volume limit 373 at 2014.02.25 20:30 exceeded)
TestGenerator: 1281 generating errors, logged 100 first error records
The goal of this job is to fix the converter script (CSV2FXT.mq4) so above error won't happen. I'm not interested in workarounds, I need the actual fix in the MQL4 source code file, and the files are NOT read-only. I can provide given CSV file where the error happens (linked above). The reason of above errors is most likely wrong calculation of volume (tick_volume) for the higher timeframes which exceeds the expected sum of it. Please provide the patched MQL4 file where unmatched data error won't happen anymore.

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.
