Hello Trainers,

New to the PCF writing so I was hoping someone could help me with the following.

- scan to show stocks with low above top Keltner channel line (2.25ATR, 20period Exponential)

- scan for the opposite (high below Keltner bottom channel line)

For now last bar is fine, ideally I would like to have 10 bar look back.

Thank you for your time and assistance.

A Condition Formula for the low being above the top Keltner Channel 20, 2.25 can be written as follows.

You can use a Condition Formula as the Boolean Formula in in a Custom PCF % True Indicator with its Average Type set to Simple to determine the percentage of the time the Boolean Formula was true over the Period of the Custom PCF % True Indicator.
