I have a strategy that tracks the Y axis of the mouse pointer with ChartControl.ChartPanel.MouseMove += new System.Windows.Forms.MouseEventHandler

Everything works fine if I open a brand new chart. Anytime I reload ninjascript it appears my MouseMove is no longer tracked and it stops printing to the screen. The only way i can fix it is if I close the chart and open a brand new one.

I am handling it in OnTermination().

Any ideas?

Below is the sample code if anyone can help

 

Code

#region Using declarations using System; using System.ComponentModel; using System.Diagnostics; using System.Drawing; using System.Drawing.Drawing2D; using System.Xml.Serialization; using NinjaTrader.Cbi; using NinjaTrader.Data; using NinjaTrader.Indicator; using NinjaTrader.Gui.Chart; using NinjaTrader.Strategy; using System.Windows.Forms; #endregion // This namespace holds all strategies and is required.

You need '-=' instead of '+=' to remove the handler in OnTermination.

Rookie mistake

Dont know how many times i looked at that and didnt catch it.
