Theoretical Option Price pullback

[epete]

Looking for code that would indicate a Theoretical Option Price (TOP) pullback. For example, I'm in an option trade, TOP is going up, reaches a maximum, then begins to pull back down. I would like to know the percentage of that downward pull back. I would like a label that indicates that percentage. So if maximum TOP is say 40 and it falls to 20, the TOP pullback percentage would be 50%.

it sounds like you want the percent change after a peak.
here is a rough outline of one way

input sym = "-";
def cls = if sym = "-" then close else close(sym);
bn = barnumber()
hc = find highest cls.
highestall or look at x bars before and after current bar.
hcbn = find barnumber of highest cls
after = bn > hcbn
percent = round(((hc-close)/hc)*100,0)
addlabel(after, percent + "%", color.yellow);
