How to write an alert comparing MACD and SToch

Hi Howard.
Thanks for all your great work and dedication. I am trying to program an alert where in the same subwindow I have a stochastics and a MACD. Visually I can see where they cross on the screen subwindow yet when I write an alert for this it doesn't work.

Hi,

Yes, STO and MACD are using different scales. However, the alert for the MACD can
use the Study as % Scale to convert it to a 0..100 value which is then comparable with STO
which is already 0..100.

Here is my alert setting to compare STO in dark blue with MACD in cyan.

Sincerely, Howard Arrington
