Vertical line is not drawn at specified time?

[Skechers]

Hello there,

I'm trying to draw a vertical line as specified (e.e. 9:30 AM EST). However it is drawn somewhat earlier than that.

My code is:

       
PrintCSV(LogWindow, "================================================================================================");
PrintCSV(LogWindow, "\"Strategy: Trading Opened. DayProfit " + DayProfit.ToString(format) + " Day Profit Target " + DayProfitTarget.ToString(format) + " Day Stop Loss " + DayStopLoss.ToString(format) + " Strategy Profit " + StrategyProfit.ToString(format) + "\"");
PrintCSV(LogWindow, "================================================================================================");
Draw.VerticalLine(this, "Trading Open " + CurrentBar.ToString(), 10, Brushes.Lime);​

As captured in the log the code is executed when current bar is 9:30EST.

But the line is drawn at 8:47AM EST.

Many Thanks! Caesar.

Hi Caesar, thanks for writing in. This is happening because OnBarUpdate has ran for the second to last bar (assuming the script is running OnBarClose) Here is a test that draws the line 10 bars ago and also marks the bar where it was drawn:

protected override void OnBarUpdate()
        {

                if(CurrentBar < 10)
                    return;

                Print("Drawing Line 10 bars ago at " + Time[0] + " " + CurrentBar);
                Draw.Dot(this, "DOT", false, Time[0], High[0], Brushes.Cyan);
                Draw.VerticalLine(this, "Line", 10, Brushes.Lime);
            ​
        }​

The alternative is to run the script OnEachTick and run this code on the first tick of the bar:

        protected override void OnBarUpdate()
        {
            if(IsFirstTickOfBar)
            {
                if(CurrentBar < 10)
                    return;

                Print("Drawing Line 10 bars ago at " + Time[0] + " " + CurrentBar);
                Draw.Dot(this, "DOT", false, Time[0], High[0], Brushes.Cyan);
                Draw.VerticalLine(this, "Line", 10, Brushes.Lime);
            }​
        }​
