TestGenerator: unmatched data error

 

Hello people,

Please help me with a solution to this error.

I know that is a problem with matching data from a smaller time frame, but i can't find any solution to convert the m1 timeframe to the timeframe that i need. I tried with period_converter, as i read in another topic, but unsuccessfully. The converter doesn't work. So any other solutions or some advice please??? 

Thnx.
