Issues after the test ended with changing tabs on strategy test continue on 5232. See that I'm on M30, but have clicked on Daily tab.


 

Just a summary of scattered posts that I noticed, related to the "tabs" malfunction in the Strategy Tester ...

MT5 Since 5200 Strategy Tester is not updating different timeframe charts

AMuxi, 2025.08.23 22:09

Hi all,

since the update to 5200 (and now with 5227) the strategy tester is not updating the charts if i switch between different timeframes.

My expert uses 3 different timeframes - 3 indicators with separated times.

After this 5220 update in the bottom of the tester chart three tabs are displayed (Daily, M30, M5). But if i select another tab, the chart is not updating - the tabs are switching, but not the content of the chart.

If i switch during the expert is running/testing, the chart switching is correct. But if the expert is finished, no chart update can be triggered. So i cannot analyze the expert logic and actions.

Is this a known bug? I didn't found the issue here in the forum.

Kind regards

Andreas

VERSION: 5.00 build 5200. Strategy tester. Windows with different timeframes.

Marcelo Lacerda , 2025.08.11 20:55

Good afternoon everyone.

Before installing build 5200, I could see two different timeframe charts in the strategy tester: 5m and 1m. Now, in this build, MT5 opens two chart tabs, 5m and 1m, but both windows are the same, 5min. I need to see the tests on both timeframes for my analysis. Has anyone else encountered this issue?

New MetaTrader 5 Platform Build 5200: Extended OpenBLAS support and enhanced control in MQL5

After updating the 5200 version, although the display interface for different periods after the backtest was fixed, the cycles could not be switched. I hope the official will fix this bug as soon as possible.
