I want to test the Z Strategies with another broker.
Since the Assets, which I get with the download script are partial wrong, I have to adjust some values by hand.
But for the PIP and PIPCosts its not clear to me.
Should I use the PIP and PIPCosts provided by the broker,
or should I use the values from the AssetsFix file, since I will test the strategies with the history files from the zorro download page?

The best way to update the AssetFix file is to use the download.x script provided and download the data directly from the broker.
If possible I would download all the data from the broker.

Are there so much difference in the price data?

Unfortunately MT5 only provide historical M1 data for the last 12 month.
I will try to store the data from the srategy tester.

I do not know, but if is possible, why not...
