"When testing in an EA, we can handle custom events using the OnChartEvent() function, but in the indicators, this function can not be called in the tester. Even if the indicator has the OnChartEvent() event handler and this indicator is used in the tested EA, the indicator itself will not receive any custom events."
Any other way to send information from the EA to the indicator?
You can use Global Variables of the Client Terminal.
May I ask why you want to communicate from EA to indicator ?
This way I can only send data to the indicator during the initialization.
That's not instant, but it's a good option, thanks.
It's not a real indicator, I want to use it to display some information calculated by the Expert.
