Mr. Larry Williams, in his book, " The Secret of Selecting Stocks for Immediate and Substantial Gains ", gives his formula for Accumulation/Distribution as:

H-Yc = B1          B1 = O if Yc > H

C-L = B2

B1 + B2 = TB

Yc -L = S1         S1 = O if Y < L

H-C = S2

S1 + S2 = TS

TB = %B  DIVIDED BY  TB = TS           %B = VOL. = OBV

Can anyone tell me if this is the formula tc2000 is using for the William's A/D?  If not, can anyone tell me how to make this into a PF formula?

Thank you.

If you create a Custom PCF Cumulative indicator in TC2000 with the following settings:

Up Condition: C > C - 1
Down Condition: C < C - 1
Value to Add/Subtract: (C < C1) * (H + C1 - 2 * C + ABS(H - C1)) / 2 + (C > C1) * (L + C1 - 2 * C - ABS(L - C1)) / 2

It will duplicate the William's Accumulation/Distribution indicator in TC2000 version 12.1. I suspect the indicator you actually want could be created by replacing the formula in the Value to Add/Subtract with (it multiplies the above by volume):

V * ((C < C1) * (H + C1 - 2 * C + ABS(H - C1)) / 2 + (C > C1) * (L + C1 - 2 * C - ABS(L - C1)) / 2)

Thank you Bruce,

I can create a formula if I just use the bottom formula of your message,i.e., V*((c<c1) etc.etc., but if I try to write the whole formula, as you sent it,i.e., Up Condition: c>c-1    Down Condition: c<c-1   Value to Add/Subtract:  v*((c<c1)*(H+C1   etc.etc.,  I get an error message.   ERROR TO FORMULA     ARGUMENT MISSING NEAR /

Should I not be using the verbage Up Conditon, Down condition, Value to Add/Subtract?  Should I be inputting this verbage differently?

If you create a Custom PCF Cumulative Indicator, there are three fields. One of those fields is called Up Condition, one of those fields is called Down Condition and one of those fields is called Value to Add/Subtract.

You need to put just the formula for each of these fields into the appropriately labeled field.

Thank you, Bruce

You're welcome.
