Alert arrows won't display on crossover

[atxtrader]

I'm trying to develop an ADX study that shows an up arrow when the +DI crosses the -DI and the ADX is above or equal to a certain value (18 for example) or a down arrow when the reverse is true. As an example, at the last bar the +DI is less than the -DI and on the current bar the +DI is greater than the -DI, all while being above or equal to an ADX value of 18. Any help would be greatly appreciated.

If you are trying to draw those arrows in the price pane then you need to be aware that an efs only outputs to the same pane in which it is running (it can however color the price bars even if running in a different pane)
If instead you want draw the arrows in the indicator pane then you need to replace the yValue that you used in the drawShapeRelative() command ie close() with one of the ADX values such as for example vADXDM14_14.getValue(ADXDMStudy.PDI) so that the shape will be drawn at a value that is within the scale of the indicator
Note also that in Set2 you used the drawShapeAbsolute() function instead of drawShapeRelative().
Lastly you need to add a tagName that is unique to each graphic object and to each bar so that you do not get multiple arrows on the same bar. In the example shown in the enclosed screenshot I am using "dnarrow"+getCurrentBarCount()
Once you make these changes you should see the arrows drawn in the indicator pane in correspondence to the locations where your conditions are met

After trying to solve this on my own for two days, that's exactly what I needed, it's working perfectly now. Thank you SO MUCH for your help.
