Display arrow per direction (short/long).

[Tzachi]

When I use an indicator to show a line in a different color for goimg up or down, I would like to use a diamond up or down when color changed.

The problem is that the diamonds are printed under every bar until a new color come one. That what I am using:

DrawDiamond("UpArrow" + CurrentBar+ TickSize, 0, Low[0] - 4*TickSize, Color.Green);

How can I display only one diamond per direction (short/long) under/above the first bar when direction changed?

Thanks in advance.

Hello Tzachi,

This will depend on the conditions you're checking for.

You could for example use CrossAbove() or CrossBelow(), which tests whether or not two lines have crossed.

If your conditions are more complex than this, another approach is using bool flags to draw on only the first occurrence of the condition, and then reset the bool flag at a later point.
