Strategy tester way slower

New comment
 

Hi all, after some software updates my strategy tester got really slow, way slower than it was. On a particular system I use, I tested around 8 passes per hour. When I use it after my software update, it takes more than 24 hours to hit 12 passes. Is there anyone having an idea what to do about this? really slows down my building and testing process. have a nice weekend and thanks

The backtest process is slow because the EA creates too many objects per tick, then deletes them, and recreates them.

To resolve this, here are some ways:
- Check the EA settings for a function to disable drawing objects.

- Instead of modeling = Every tick, change it to Price Open Only.

Hope this helps you,
sincerely.

Check your version of mt5. There has been a few betas with issues lately. Albeit that Alain has reported some of these to be fixed in 5518

Forum on trading, automated trading systems and testing trading strategies

All about MT5 updates.

In case you got an BETA update, for whatever reason, and you want to move to the last official release :

  • A Telegram channel has been created, you will always find there the last official release needed exe files.
  • MT5 Terminal is available in several versions according to your CPU capabilities. You can check which version you have to use in the Journal log, at the first entries after you started MT5.

Here my version is AVX2, an other possibility is X64

  • With this information you will know which zip file to download.


  • You then just have to replace your current exe files with the ones from the Zip. If you don't know how to do, then doing this operation is probably not a good idea.

After MT5 is restarted, you will have the last official release.

If you don't want to get beta-build updates again :

  • NEVER connect to MetaQuotes-Demo server.
  • NEVER use MT5 Terminal Help menu=>Check for Updates=>Last Beta Version.

 
Share photo of your terminal, for me, i have found my problems there, sometimes entering to much orders at the same time, or calculating a lot of stuff in each tick.
