The ICustomWidgetChartObject chart object can be used as a container for user's own JPanel and its contents. Note: The feature is available with JForex-API 2.7.11.

Example

Consider a strategy which creates a chart widget with two buttons - one which draws prices lines and the other one which makes BUY market orders.
