Cross over arrows

[the_one]

I have absolutely no programming abilities, so it would take me years to be able to create the two studies I need. I am hoping that someone can help me create a cross over arrow similar to the one found in the macdx-over2 study in the JasonK formulas. I need the crossover arrows in two studies: the Chaikin oscillator with ma study and the maofobv study. I have attached both of these. Thank you in advance.

Here is the other attachment. Oh and thank you to the original creators of those studies.
