I would very much appreaciate if you add into IIndicator interface method onStop() (or similar named) which would be called on the indicator remove from the chart... It is necessary for me because I use in the indicators opened streams as database or file... Or create a new interface with this method because of compatibility...
IStopListener is not available in SDK JForex-API 2.12.30. It is not present in JavaDoc https://www.dukascopy.com/client/javadoc/ in com.dukascopy.api.indidcators. Also IIndicatorsProvider does not offer method: addIndicatorStopListener.
