Arrows not drawing on tick charts

[meandthetrio]

I am developing an indicator that will use arrows and simply put these arrows will not draw on tick or renko charts, only on minute charts, right now I am just trying to get them to print:

protected override void OnBarUpdate()
{
if (Close[1]>Close[0])
DrawArrowUp("tagA"+CurrentBar, 0, Low[0] - 3 * TickSize, Color.CornflowerBlue);

Again, using this code they print on time charts but no other type. I am using NT7
Thanks in advance!

Hello meandthetrio,

Thanks for your post.

We've moved your topic into "NinjaTrader7 indicator development" just to keep NT7 and NT8 separated as the methods and properties can be different between them. Please help us keep the forums organized by posting in the appropriate topics, thank-you.

I would suggest adding this line of code just above your if statement: if (CurrentBar < 1) return; // wait until 2nd bar before proceeding

If you look at the log tab of your control center, you may see errors listed there concerning bar index error. The conditional check of the CurrentBar is to ensure that at least 1 bar gets loaded before the indicator tests to see if the current bar [0] is less then the previous bar[1]. The indicator, when it loads, will always start at the first bar of data and on that first bar there is no [1].

The reason why it may show on the time based bars but not price based could be coincidental related to the condition used, Close[1]>Close[0].
