If a Strategy module places objects on a specific chart, it can happen that another chart has exactly that same key identified object (perhaps from a previous run, and the key chart object was not removed).

Is there a way for a Strategy module to iterate through ALL charts and to remove these duplicate keys, so it can proceed on its desired chart?

What is the recommended way of handling this issue in Strategy code from within the JForex platform environment?

I hope that made sense.

You can iterate through all charts the following way:

And then call IChartPanel.getAll(). Note that the key uniqueness is not IChart-bound, rather IChartPanel-bound. Hence, if your strategies draw on indicator panels, then you would also need to iterate through IChart.getIndicatorPanels().
