What about using the clipboard ? I think i read something to this effect in another post of yours recently.

I haven't had the need tor two charts to talk to each other, but I get an indicator to talk to a strategy using this: //### This is for External strategies. //### Update() ensures this exposed variable is up to date, when external strategy Add()'s this indicator public string TradeCommand { get { Update(); return tradeCommand; } Set { tradeCommand = value; } } And I get one indicator to share variables with another indicator like this: public class GlobalChartVars { public static Dictionary<string, string> chartIds = new Dictionary<string, string>(); public static Dictionary<string, string> SoundFiles = new Dictionary<string, string>(); } I think the 2nd one should be able to share data between charts. I haven't tried it that way, but maybe that can give you some ideas.

You could probably use that as well, but requires more coding then it is probably worth just to access the data in one variable.

Monpere or anyone who knows, Does the code snippet above, in the strategy force the Indicator to Update its value or does it only update its own copy of the Last external public value published by the indicator.

You're better off using a Singleton design pattern, and then writing semaphores around the get/setting of the singleton instance's shared data. If you want data "sent" to interested parties when changes are made look to implement INotifiyPropertyChanging.
