Tickstory

Does this still hold true, now making the spread box in Tickstory largely irrelevant?

The currency for the DAX is EUR. I would be making sure that the 'margin ccy' field is also set to EUR, as it seems that the MT4 strategy tester is trying to perform some sort of conversion. Note that is MT4 error is not documented, so resolving this is a matter of trial and error. The other thing ...

The "server name" (eg. "Alpari Demo") that you are exporting to should have a default account currency when it was set up. You need to have logged in at least once to your MT4 terminal so it could download the default broker configuration. What is the symbol currency for DAX? The accounts I had bee...

There is some discussion on this topic in the MQL groups. One suggestion is that your account's currency must match the symbol currency. Is this the case?

Regards.

Which account's currency if I am not logged into any account while using MT4 with Tickstory?

I used Tickstory's "Map to" option for the DAX symbol name discrepancy but I am now getting this message: 2015.09.11 12:11:57.002 Tester: exchange rate cannot be calculated. I've set the base currency to EUR in Tickstory before re-downloading the data and keep getting the same message in the journal...

That's a good question and is best answered by MT4 developers. You could ask the question on MT4 forums, however given that this method of tick-quality back-testing is not officially supported, I'm not sure whether you'll get an official answer. There may be other users who have worked around the i...

Things go great in that case. I am more curious about the roots of this problem. Why does a bigger file size (yet under the 4gb limit) cripple the backtesting?

No it doesn't. It only writes HST and FXT files specific to the symbol being exported. If you believe that something is changing in-between exports, why not try exporting both symbols before commencing the back-tests? Tried that. Upon the completion of the download process for both pairs, I run a E...

The only thing that changed was the download of historical data for another currency pair. Does it somehow replace the previously downloaded data for the other pair?

Does it work again if you restart MT4? If so, it sounds like something odd is happening within MT4. I'm guessing that your FXT files are under 4gb? You might need to try reducing the file size further to get some consistency. No, it's the same issue even after restarting MT4. Only the lengthy re-do...
