    Labelled lines

    Just a little feedback for the author (NT staff, I believe).

    To prevent unhandled 'null' errors (object reference not set to an instance of an object), labeled lines onRender needs to be updated with the following (or some equivalent), because you will still get an "NinjaTrader.NinjaScript.DrawingTools.DrawingTool. **GetAttachedToChartBars**(...) returned null." error with the current null detection

    Code:
            public override void OnRender(ChartControl chartControl, ChartScale chartScale)
            {
                base.OnRender(chartControl, chartScale);
    
                Stroke.RenderTarget         = RenderTarget;
                OutlineStroke.RenderTarget    = RenderTarget;
    
                try
                {
                    if (GetAttachedToChartBars().Bars.Instrument.MasterInstrument == null)
                        return;
                }
                catch
                {
                    return;
                }
    Regards,

    Paul

    Try this instead

    Code:
    ChartBars tcbs = AttachedTo.ChartObject as ChartBars;
    if(tcbs == null) { Print("ChartBar Problem"); return; }
