Hi boatman,

thank you for your tips! I will read those points very carefully.

"complete and absolute control" point to the fact that I have downloaded and validated my historical data from Dukascopy, I have no problem to create historical data for the various time-frames or adding a fixed or variable spread.

Another little question... does Zorro allows tick-by tick back-tests? As far as I know the answer is no (not a big problem to be honest).
