Showing Inside/Outside Vertcal bar formation on chart

[MiamiTom]

I am trying to show where the inside and outside vertical bars occur on my charts but it will not display. I would like to display a simple text of "IVB" or "OVB" display above the bar when it occurs. I am not sure why it is not displaying. Can you guide me?

if (High[0] > High[1] && Low[0] < Low[1]) // Outside vertical bar
DrawText(Convert.ToString(CurrentBar+"OVB"), "OVB", 0, High[0] + (8*TickSize), Color.Red);

if (High[0] < High[1] && Low[0] > Low[1]) // Inside vertical bar
DrawText(Convert.ToString(CurrentBar+"IVB"), "IVB", 0, High[0] + (8*TickSize), Color.Red);

Thank you.

Hello MiamiTom,

The logic looks good. Check the log tab of the control center for any error messages.

You may be running into this issue here.

Receive error as follows:

Error on calling the 'OnBarUpdate' method for indicator 'InsideOutsideVB' on bar 0: Index was out of range. Must be non-negative and less than that size of the collection. Parameter name index.

Yes, that would be the issue described in Make sure you have enough bars in the data series you are accessing.


Add the lines below in your OnBarUpdate() block and it should resolve for you:

if (CurrentBar < 1)
return;

Not sure why this works but it did. Text now showing.

Thank you very much.

Glad that did the trick for you. Thanks for the update.

The [1] index value does not exist when attempting to access from the first bar in the series. The statement you added tells NinjaTrader not to process the indicator logic for this first bar.
