I use the "Export for MT4 (FXT and HST)" function to make backtest with tick data precision.
Before the export I select my broker's symbol properties using .QDM file generated with your script.
It seems that except for forex datas, all other symbols are copied to MT4 with wrong parameters, whith don't allow MT4 to execute a backtest.
I've tried with commodities, metals, indices and I get the same error: "tester cannot calculate prices".
The only solution I've found is to correct properties with "property editor" provided with Tickstory.
Can you please check and fix this problem?
Thanks and best regards
