I get the following error on line 24 when I tried running this system.
Error Cannot implicitly convert type 'System.Collections.Generic.IList' to 'System.Collections.Generic.List'. An explicit conversion exists (are you missing a cast?) c:\Research\Code\Simple Crossover\Simple Crossover.cs 24
When I tried casting the result of the GetOpenPositions using "(List)", I get the following runtime error:
An exception of type System.InvalidCastException was thrown.
Unable to cast object of type 'System.Collections.ObjectModel.ReadOnlyCollection`1[RightEdge.Common.Position]' to type 'System.Collections.Generic.List`1[RightEdge.Common.Position]'.
at SystemMain.NewSymbolBar(Symbol symbol, BarData bar) in c:\Research\Code\Simple Crossover\Simple Crossover.cs:line 24
Would you please repost a version of this system that works with the latest RE build?
Thanks
