Backtesting issues, mainly Modelling Quality n/a

Hi, sorry I could not help because of limited knowledge.. But can you tell me how you specified the location for MT4 installation?
As I know indicators etc in MT4 build 670 has been moved to another location, might be only accessible by “Open Data Folder”, which I cant locate it through tickstory window..

Hi Armnic,

Thank you for your detailed post. The problem seems to relate to the launcher and the fact that in step 2 you are getting the launcher error (there is no need to have pressed the ‘Like’ button). We have tried downloading a fresh copy of Metatrader from Metaquotes.net with Build 670 and have no issues. Can you please try to see what happens if you press ‘launch’ again after MT4 has been started? If you see the title of the MT4 window change to indicate “Tickstory Launcher” was successful, then your back-testing should yield you 99.9%.

I’m assuming that you are using Windows 7+?

Thanks.

Hi Josip,

The problem you describe appears to be different to that of Armnic – the original post seems to suggest that the launcher is not working resulting in a “n/a” modelling quality. In your case, however, you are suggesting that a particular date is causing your back-test to stop. As you are aware, having an FXT file larger than 4GB will cause the back-test to stop whenever MT4 finally can’t handle the amount of data. As per your suggestion, we have tried to export a specific date range to try replicate your problem:

– Using MT4 Build 670 (downloaded from Metaquotes.net)
– Exported EURUSD from 1st April 2014 to 1st May 2014 with default settings (timezone, etc).
– Launched MT4 via Tickstory.
– Back-tested EURUSD with the standard “MACD Sample” EA in “Every tick” mode, M15 period.

The results yielded the expected 99.9% quality and the back-test did not stop until the end of the period (trades were taken up to the 30th April 2014). There was no “close at stop” at the end of the period.

Do note that depending on when you start your back-test, your EA could be the culprit if the draw-down during the start period is too much. The “close on stop” problem usually indicates that the back-tester needs to close your trades for some reason – typically blown account. Looking at the 15-minute chart for the 29th April, there was a major dip in price.
If you still believe it is the data causing the issue, you can check the MT4 Historical Data center for any anomalies. Generally speaking, however, if you are able to run the MACD Sample EA across the data with no problem, it wont be the data causing your issue.

Hope this helps.

P.S. Please note we may split this thread to ensure there is no confusion between this issue and that of the original poster.

Hi Armnic,

Thanks for your update. It seems that you might need to resolve the access prompt you are getting before things work correctly. What might possibly work is to wait until MT4 has been launched and then press F8/Launch again in Tickstory.

The changing of the title bar is not a biggie as long as you’re getting 99.9% modelling quality. Sometimes MT4 will refresh the title bar when charts are opened/closed.

Hope this helps.

Hi London,

Have you tried the suggestion above? Press the ‘launch’ button again once MT4 has fully loaded.

Regards.

I tried to Launch MT4 through Tickstory Lite app. However, it is not launching MT4 platform (FxPro)
