In beta, retrieves the error, and usually only recovers the first "1" data.
It gives an error when compiling one program:
Is this the 535 build?
Most probably you opened the file "C:\Program Files (x86)\Alpari NZ MT4 #4\experts\indicators\Channels.MQ4" and tried to compile it?
You need to manually move your own files from your local experts directory to "C:\Users\user\AppData\Roaming\MetaQuotes\Terminal\8F311E250E67877D0B9CF7826D598895\MQL4\", with experts put in \experts subdirectory, indicators in \indicators etc.
We have not yet completed the automatic migration of custom programs from the old \experts directory. Only MT4 regular programs are migrated at the moment.
Build 535, I can not understand why these errors:
2013.11.08 00:17:06 TestGenerator: unmatched data error (high value 1.32643 at 2013.01.02 12:00 is not reached from the lowest timeframe, high price 1.32642 mismatches)
On the 509 build, everything runs smoothly. Why price is not correct?

Yes, it was. Your advice helped! Let's keep checking!

You need to recreate all timeframes based on the minute timeframe, using the in-house period_converter. Remember to delete all older timeframe files in the history folder before creating them.

This is what I started to get
The RAM build 535 is loaded
The strange thing is that after restarting the terminal and reinstalling the EA everything works, but after recompiling the EA
it shows this error. There was a time when I put the EA on a chart and at the first tick the EA was deleted from the chart ...
So now you have to create everything manually and it won't work like before? Or is this temporary while testing is going on?
I do this before every serious history test, if we are talking about checking the strategy and not the code. The matter is that up to the 509th build a new history (the one that comes online) in the terminal is accumulated on the basis of nine sources (by the number of timeframes), because of what there may be differences in timeframe data. In MT5 we took a different way at once: all TFs are built on the basis of M1. As far as I understand the new MT4 will do the same. As a result we will never see mismatch errors again.
