I was hoping you can help with creating a PCF for TC2000 V.7.  I would like to create a PCF that has a 5 period bollinger band with a 1 standard deviation (5,1), and identifies when the percent B is 0.1 or less.  Thanks

Please try the following:

(C - AVGC5) / 2 / SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 - 5 * AVGC5 ^ 2) / 4) + .5 <= .1

Thanks Bruce.  The above PCF is identifying many stocks that are greater than .1, even above the upper band of the 5-period bollinger band?

Please disregard the above post.  I just reinstalled TC2000 due to installing a new operating system and didn't correctly update PCFs.  The code you provided works well.  If you don't mind, how would I create a scan for %B to be multipe consecutive days below .1, i.e., 4 days in a row?   Thanks

Please try the following:

(C - AVGC5) / 2 / SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 - 5 * AVGC5 ^ 2) / 4) + .5 <= .1 AND (C1 - AVGC5.1) / 2 / SQR(ABS(C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 - 5 * AVGC5.1 ^ 2) / 4) + .5 <= .1 AND (C2 - AVGC5.2) / 2 / SQR(ABS(C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 - 5 * AVGC5.2 ^ 2) / 4) + .5 <= .1 AND (C3 - AVGC5.2) / 2 / SQR(ABS(C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 - 5 * AVGC5.3 ^ 2) / 4) + .5 <= .1

Thank you!

You're welcome.
