Z7: Using t1 instead of t6 history data

Hi,
We recently decided to train and test Z7 strategy (Zorro S license) on t1 data history (provided by Zorro) for EURUSD, and for this purpose we removed GBPUSD, USDJPY, EURUSD t6 data from history
folder and placed there only EURUSD t1 data, downloaded from zorro website.

We faced the following problems trying to test and train the strategy:

1) train resulted in this log message
