Hello Shai Samuel,
Thank you for writing in. While there is no way to prevent a user from attempting to add multiples of the same indicator, you can add a check in your indicator so that it simply returns if it has been added more than once.
For example:
Code:#region Variables private bool alreadyExists = false; #endregion protected override void Initialize() { foreach(Indicator i in ChartControl.Indicators) { if(i.Name == "myIndicator") //Replace with the name of your indicator { alreadyExists = true; return; } else { //Initialize the indicator } } } protected override void OnBarUpdate() { if(!alreadyExists) { //your OnBarUpdate() code goes here } }

Thank you Michael, this is really helpful.
koganam, what I would add to this code, is a Log message with NinjaTrader.Cbi.LogLevel.Alert, and return.
