The "Other Instances Found" error occurs when the Expert Advisor (EA) detects multiple active instances of itself on the same account or symbol, which can lead to conflicts.
To trade on all pairs listed in the 'Symbols' parameter, you only need to install one copy of the EA.
Here’s how to resolve the issue:
Check for multiple instances of the same EA on different charts.
- Ensure that only one instance of the same EA is running on any single chart.
- To remove any duplicate EA, right-click on the chart, select "Expert Advisors," and then click "Remove." Alternatively, you can simply close the chart.
