drawing updating from input file

[tonynt]

Hello,

I draw horizontal lines in my chart and calculate in my script with values from a csv file. All works fine but I have the problem that when the csv files calculates new levels (from excel) then I have to refresh in NinjaTrader with F5 so that the values are to use in the script.

I tried to do this automatically in onbarupdate with

if(readlevels == 0 && ToTime(Time[0]) > 93100)
{foreach(LineInfo item in _filevalues)
{readlevels = 1; // set int for no more reading
if(item.LevelText == "L1" && item.LevelValue > 0)
{L1L = item.LevelValue;}
f(item.LevelText == "L2" && item.LevelValue > 0t)
{L2L = item.LevelValue;}
......
......

if(item.LevelText == "L1" && item.LevelValue > 0) {DrawHorizontalLine("L1L", false, item.LevelValue, Color.Peru, DashStyle.Dash,1);}
if(item.LevelText == "L2" && item.LevelValue > 0) {DrawHorizontalLine("L2L", false, item.LevelValue, Color.Peru, DashStyle.Dash,1);}
}

but it doesn´t draw the new levels at that time. I have to press F5. How can I have the updated values working in the script without pressing F5? What I´m doing wrong?

Thank you
Tony

Hello tonynt,

Thank you for your note.

If OnBarUpdate() is not seeing the new values you may need to force a new "read" of the file. Do you have an example script and file we could test your logic in?

Have you tried refreshing the chart?

        // send repaint message to chart window
        protected void RefreshChartWindow()
        {
            if (ChartControl != null)
                ChartControl.Invalidate(true);
        }

Look in @BarTimer.cs and @Pivots.cs for examples.
