I just want the indicator to give an arrow up or down as RSI crosses the 50 midline.
It plots OK, but no arrows.
I got the arrow conditions piece from strategy wizard.
The only code difference in the RSI indicator itself is I eliminated plotting the Avg line and overbot/oversold lines. so all I draw is RSI and the 50 midline.
