well, it sounded to me like he was talking about something a little different.
anyway, your video was very helpful, thanks...

which of these formula do i use?
when i try and create a new pcf (via cut and paste) i get a syntax error?
General Bollinger Band formula
BB(Pds,SDs)= SMA(Pds) +/- SDs*StdDev
Add/Sub final term to get Top/Bot BB
Middle BB line = SMA(Pds)
Standard Deviation PCF (per TC plot)
SQR( ( ( C*C + C1*C1 + ...+ Cn*Cn )
- ( p * AvgCp * AvgCp ) ) / n )
where p = SMAPds and n = Pds-1
Example: Pds = 10 days, 2x SD Top BB
TC requires 2x to be input as "20"
BB(10,2) = AvgC10 + 2 * SQR((( C*C +C1*C1
+C2*C2 +C3*C3 +C4*C4 +C5*C5 +C6*C6
+C7*C7 +C8*C8 +C9*C9 ) - ( 10 * AvgC10 *
AvgC10 ) ) / 9 )
Example: Pds = 20 days, 1x SD Bot BB
TC requires 1x to be input as "10"
BB(20,1) = AvgC20 - 1 * SQR((( C*C +C1*C1
+C2*C2 +C3*C3 +C4*C4 +C5*C5 +C6*C6
+C7*C7 +C8*C8 +C9*C9 +C10*C10
+C11*C11 +C12*C12 +C13*C13 +C14*C14
+C15*C15 +C16*C16 +C17*C17 +C18*C18
+C19*C19 ) - ( 20 * AvgC20*AvgC20 ) ) / 19 )

craig,
i got that far already.
for someone with minimal coding knowhow, this is a difficult exercise.
im sure you answer a lot of stupid questions.
im just trying to make a living here.

my last post i asked about sorting stocks by the width of the bollinger bands.
another user tell me:
Further suggestion: search for Bollinger Bands in the PCF's Board to find the custom indicator formula for BB bandwidth (i.e N * Standard Deviation).
Now apply a separate 60SMA child indicator to that plot, and look for cases where the Width is below the SMA.
Better yet ... apply a 60,20 BB child indicator to the custom width indicator ... look for cases where the width is below the lower BB.
You can use Comparative SortBy to assist with this.
how do i do this?

thanks buddy:)

thanks:)

btw the criteria for this would be:
-the band witdth increased by 1 point (this is arbitrary)
-the stock price needs to be within 2 points of the 30 day low (2 points is arbitrary also;)
|
the idea is that a 'squeeze' occurs when the bollinger band width is the lowest value (narrowest) it has been for 6 months...
is it possible to 'sort' for this? i.e. stocks that have the narrowest band width in 6 mos.
if i need to write a pcf would it be possible to give me some direction.
thanks,
