I may be able to help, at least until Bruce hops back on
STDDEV20*4 <= 3 * ATR20 is the correct PCF for Squeeze On in V17. If I were writing a Scan Condition, this is the formula I would use
The other format is a "trick" Bruce is using to make the charts cleaner when plotting dots to show when a condition is true or not. The "trick" works for other indicators as well, not just the Squeeze.
Normally, when using Dots to indicate whether a Condition is True or Not, we end up with two dots, one for True, and one for Not True. The PCF Indicator used is Custom PCF % True and Scaling is set to determine where the Dots should be placed.
When using the "trick",Custom PCF Indicator is used (not the True) version). The PCF uses the 0/(Formula) (0 / (STDDEV20*4 <= 3 * ATR20 in this case) to return a value only when the Denominator =0, otherwise it returns a Divide by Zero value, which is NOT plotted. The result is a single set of dots plotted on the zero line and only under one condition. The row of dots seen at the bottom of the chart panel if using Custom PCF % True is not seen using this this technique
General form of High PCF Element is
MAXwx.z -> Maximum Value of Price Component or Volume over a specified span of bars ending on the specified bar (w must be O, H, L, C or V)
So I think you would want
MaxC30 = MaxC7 or, if you wanted to scan for the condition 1 bar ago
Bruce, posting the following for your thoughts:
I have a similar signal, with three preconditions and two elements in the trigger
Not being sure that there would always be a consistent order that the crosses would follow, and wanting more than one day to become aware of the signal, I coded the trigger elements as follows:
Bruce, if she wants to view the scan results from yesterday,could this not be done with Custom Date Sort?
Took me a minute to figure out (I think) what is meant by the two different uses (had some wine with dinner)
Function Version: Use if I want to plot directly on chart
Indicator Version: Use if I want to use within a PCF
Am I correct?
Wine was Kirkland (Costco) Old Vines Zinfandel - recommended
Believe it or not "RGW" is supposed to be THE - I was in a darkened hotel room at the time :-)
Bruce, what is the significance of the brackets around the x,y, z variable?
Example: What is rgw difference between
WRSI(x, z) -> Wilder's RSI (Wilder's Smoothed)
WRSIx.z -> Wilder's RSI (Wilder's Smoothed)

Asimple crossover PCF for what your text says you want is:
C>XAvgC3 and C1<XAvgC3.1
which says the CLose today is greater than XAvgC3 today, but was less than XAvgC3 yesterday
