Confusing BarsAgo return

[Chippy]

The following code returns a large negative integer for an object drawn on a chart, ChartAnchor.BarsAgo when the expected number would be 10 or so. Please explain.

int x=0;
drOb = DrawObjects.Count;
if(drOb >0){
   foreach (DrawingTool draw in DrawObjects.ToList()){
      foreach(ChartAnchor myAnchor in draw.Anchors.ToList()){
         if(draw.IsUserDrawn){
            Print(myAnchor.Price +" " + myAnchor.BarsAgo);
         }
     }
   }
}

The following code works as expected and was the intent of the above failed code. I'm just wondering why BarsAgo wasn't working in that case.

int =0;
drOb = DrawObjects.Count;
if(drOb >0){
   foreach (DrawingTool draw in DrawObjects.ToList()){
      foreach(ChartAnchor myAnchor in draw.Anchors.ToList()){
         if(draw.IsUserDrawn){
             x=CurrentBar - Bars.GetBar(myAnchor.Time);
            Print(myAnchor.Price +" " + x);
         }
     }
   }
}

Hello Chippy,

Thank you for your reply.

<ChartAnchor>. BarsAgo will NOT work on manually drawn objects. This property is reserved for chart anchors which were drawn by another NinjaScript object (e.g, using a Draw method in an indicator). For manually drawn objects, please see the SlotIndex property.

Please let us know if we may be of further assistance to you.
