API 3.8 Problem - Cross-Symbols, Drawings(Object) objectname.CrossSymbol = true; its Missing - Objects Deleting

 I would like to say that, in my opinion, your platform is much better than mt4 or mt5,  they crash alot.

 so thanks very much its really appreciated.

O.K regarding the problem

           var rectangle = Chart.DrawRectangle(name , x1, y1, x2, y2, color);
            rectangle.IsFilled = true;
            rectangle.IsInteractive = true;
            rectangle.IsLocked = true;

            rectangle.CrossSymbol = true;     is missing

This, now - since new API -  has cause a problem for

        private void OnChartObjectRemoved(ChartObjectRemovedEventArgs args)
        {

        }

It now deletes the objects when the symbol changes,   its ok if you change timeframes.

perhaps there is another way to stop it?

thanking you

kind regards
