Hello leojimenezp,

To do this in a drawing tool you would need to do that from OnRender. You would need to set a class level variable to the value that the quantity selector has.

private int quantity = 1; 
public override void OnRender(ChartControl chartControl, ChartScale chartScale)
{​

   chartControl.Dispatcher.InvokeAsyn c((Action)(() =>
   {
      NinjaTrader.Gui.Tools.QuantityUpDown quantitySelector = (Window.GetWindow(chartControl.Parent).FindFirst(" ChartTraderControlQuantitySelector") as NinjaTrader.Gui.Tools.QuantityUpDown);

       quantity = quantitySelector.Value;
   }));
}
