You must have meant deleveraging.
Agree, my mistake. I should have written, re-design the system.
The point I am making is that if a system trades one ES per 200K, in my opinion it is a very poor system.
Perhaps a simpler approach, if possible, would be to re-write your risk parameters thus bringing down the funds needed to properly trade one ES contract.
Sam,
Most likely the problem is with silverlight itself. Once you put too many drawing on the chart the app goes nuts.
Habitually go to 'drawings' and delete all drawings.
Hope that helps.
