Display lines on a 1 minute chart for each 30 minute high and low?

[tommyjames]

Is there any way of displaying lines on a 1 minute chart for each 30 minute high and low?

 

Thanks

Here is a paintbar that would do it (aren't paintbars neat?)

double High30 = 0;
double Low30  = Double.MaxValue;
double X1     = -1;
double X2     = -1;

public void MainCalculation()
{
    if (Timestamp[0].Minute % 30 == 0 || X1==-1)
    {
        High30 = High;
        Low30  = Low;
        X1     = CandleNumber;
        X2     = X1+0.5;
    }
    else
    {
        High30 = Math.Max(High30, High);
        Low30  = Math.Min(Low30, Low);
        X2     = CandleNumber+0.5;
    }
    SetLine(X1+0.1, SysColor.Positive, X1,High30,X2,High30);
    SetLine(X1+0.2, SysColor.Negative, X1,Low30,X2,Low30);
}
