Need Help with plotting line at the open price on the hour

[dpanglin]

Below is my attempt at coding what I am asking for but has compilation errors. Can you help?



{
if (CurrentBar < 24) return;
int H1 = 0;
for (int barsAgo = 0; barsAgo < 24; barsAgo++)
{
H1 = H1 + Input[barsAgo];
}
if (ToTime(Time[0]) >= ToTime(H1, 00, 00))
{
int bartime = CurrentBar - Bars.GetBar(new DateTime(2007,1,16,H1,0,0));
}
DrawHorizontalLine("Hour Open",Open[bartime],Color.Blue);
}

H1 = H1 + Input[barsAgo];
That will cause some problems since Input[barsAgo] is a double while H1 is an int. If you changed H1 to a double you will still have problems over here:
ToTime(H1, 00, 00)
The inputs for ToTime() should be ints not doubles. I am also not sure if you can use an int > 24 for the input of your DateTime variables. Your H1 variable can surely take on a value greater than 24 and cause problems in that aspect too.

Thanks Josh. Got the following to compile but still not updating my line on the hour. Any thoughts.

--------------------------------------------------
-------------------------------------------------

protected override void OnBarUpdate()
{
//if (CurrentBar < 24) return;
int H1 = 0;
for (int barsAgo = 0; barsAgo < 24; barsAgo++)
{
H1 = H1 + barsAgo;
}
if (ToTime(Time[0]) - H1*10000 < 0)
{
int bartime = CurrentBar - Bars.GetBar(new DateTime(2008,1,17,0,0,0));

DrawHorizontalLine("Hour Open",Open[bartime],Color.Blue);
DrawVerticalLine("Hour Line",bartime,Color.Blue);

}
else
if (ToTime(Time[0]) - H1*10000 >= 0)
{
int bartime = CurrentBar - Bars.GetBar(new DateTime(2008,1,17,H1,0,0));

DrawHorizontalLine("Hour Open",Open[bartime],Color.Blue);
DrawVerticalLine("Hour Line2",bartime,Color.Blue);


}

You will need to debug your code. Please check out this tip: http://www.ninjatrader-support.com/v...ead.php?t=3418

If you look in the Log tab in the Control Center you will see an error to this effect:

Error on calling the 'OnBarUpdate' method for indicator 'drawtest' on bar 0: drawtest.DrawVerticalLine: bar must be greater/equal 0 but was -251

Thanks for pointing this out. Still working on it will. See what you get if you delete the "DrawHorizontaLine" line of code.

Due to bandwidth issues I cannot help you debug your code. Thanks for understanding. I suggest you us Print functions on your H1 values and your bartime values in the manner recommended in the tip I provided you.
