Hi,
Would it be possible for Dukascopy to provide an example of using the SDK to open multiple seperate charts for a backtest?
I've been working through two examples from the documentation, GUIModeMultiChart which has multiple charts but in different panes in the same window, and MainOpenWindow which has multiple seperate charts but is only for live trading. When I try to integrate the two by adding what I thought would be the required changes to GUIModeMultiChart I get error
2018-03-10 08:51:53.358 INFO MainOpenChart - Subscribing instruments...
Exception in thread "main" java.lang.IllegalStateException: It's not designed to open charts in back-testing at the moment
at com.dukascopy.api.impl.connect.TesterClientImpl.openChart(TesterClientImpl.java:644)
at MainOpenChart.startStrategy(MainOpenChart.java:141)
at MainOpenChart.main(MainOpenChart.java:60)
I've attached my attempt at integration.
Many thanks in advance!

The strategy is not allowed to open new charts when backtesting. Therefore, this is not possible.

Thanks for your response. So just to confirm, it’s not possible to open separate charts during a backtest using any functionality within the sdk? The closest would be opening multiple panes in the same chart frame (which there are examples for)?
If this isn’t possible, within the sdk is it possible to change chart instrument using a drop down box during a backtest? I’ve seen examples in the documentation, but think they’re all for live strategies.
Thanks in advance.

Charts can only be created by tester itself. Created charts are available using ITesterUserInterface.
Charts periods and feeds can only be changed by using ITesterChartController.
Standart chart creation is not available in SDK tester.
