How to Scan for a PPO Line above 0 for x number of days?
I have been trying for a looong time to figure out a way to scan for a PPO Line 12,26,9 that is staying > 0 for xx numbers of days, and which was < 0 just the day before that span of time. The scan works, yet it doesn't!
AND [MAX (30, PPO Line (12,26,9)) > 0] // PPO Line is above zero for the past 30 days
AND [31 days ago Daily PPO Line(12,26,9,Daily Close) < 0] // PPO Line was below zero 31 days ago
The scan has no mistake but it doesn't return what is expected. I find many stocks where the PPO Line was below zero from day 30 until today, while it shouldn't since the PPO Line should be above zero for the past 30 days.
Is there a way to scan for that?
