ABS(w ) -> Absolute Value Function
Where w is the Number or Indicator to which a Function is applied.
PCF Formula Descriptions
The Absolute Value Function returns the magnitude of the value. This leaves values that are greater than or equal to 0 unchanged and coverts negative values to positive values (multiplies negative values by negative one).

Thanks Bruce-not sure what that means but I'm sure I'll figure it out if I stare at it for another few hours. ;) Just kidding, an hour and a half tops should do it....
No, really...if there is a more detailed section on how to use ABS I'd appreciate being pointed to it-thanks again

I bet it really is a lot simpler than you think. It just turns all negative numbers positive.
ABS(5.63) = 5.63
ABS(0) = 0
ABS(-7.25) = 7.25
ABS(C - C1) = ABS(C1 - C) = ((C - C1) ^ 2) ^ .5
You just use it when you don't want any negative numbers. There aren't any topics to which I can point as to how to use the ABS() function, but I can point you to topics where the ABS() function is used:
CCI INDICATOR
Please provide a description and PCF for calculating an ATR value to be used as a stop loss value
RSI2 Scan

Thanks for trying Bruce-I just need to get into some PCF training videos and this will probably all come together. Thanks again

You're welcome. I wish I could think of another way to explain it. Understanding this concept is pretty much required to correctly write a formula to do what you want in Doji construction issue.
