    DrawLine using DateTime

    I used the sample code below expecting to get two 'draw lines' on the chart, one in blue at the Low and one in Black at the high. I did not get that.....(not sure what is wrong). I attached the screengrab, which shows the Blue line drawn using barsago, but no black line using DateTime.


    PHP Code:
    
    private DateTime    holdDT    =    new DateTime();
    
    protected override void OnBarUpdate()
    {
        if (CurrentBar == Bars.Count - 20)
            holdDT = Time[0];
                
        if (CurrentBar == Bars.Count - 3)
        {
                int wwBackBarNum = ChartBars.GetBarIdxByTime(ChartControl, holdDT);
                int myBarsAgo     = CurrentBar - wwBackBarNum;
                Draw.Line(this, "bars"+CurrentBar,true,  myBarsAgo,   Low[0],      0,   Low[0], Brushes.Blue,   DashStyleHelper.Dash,4);    
                Draw.Line(this, "time"+CurrentBar,true,     holdDT,  High[0], Time[0], High[0], Brushes.Black,  DashStyleHelper.Dash,4);    
        }
    }

    Hi photog53,

    Are you getting any errors in the Log tab of the Control Center?

    On the bar where the blue line is drawn, what is the value of holdDT?

      Hi photog53,

      Are you noticing that the line sometimes appears when you hit F5?

      This may be reported issue #NTEIGHT-9581 'Draw objects not drawn initially when using overload that accepts DateTime'.

      This item has been corrected for NinjaTrader 8 Beta 11.

      Once Beta 11, is available for download, please update and test for this behavior once more.

        Chelsea,
        No errors in the log.....
        The value of HoldDT was 13:20.... which the NT8 code "ChartBars.GetBarIdxByTime(ChartControl, holdDT);"
        found quite well but the Draw.Line code could not find.
        This issue also seems to be happening for Draw.Ray....and perhaps others.... which implicates the Issue you noted.

        Glad to see this will be corrected in beta 10.

        Thanks....
