I have downloaded m1 quotes for Ger30. And used the period converter to on this quotes for creating the other timeframes.
When I do a strategy test on M1, I've got 25% data quality with NO Charterrors.
When I do the test on M5 I've got many charterrors > 10.000.
How could this happen? Does this mean, that the most prices for an indicator out of M5 are wrong?
