Dear SIr or Madam,

 I have two questions to ask you.

1) Could you please explain me the formula for the calculation of the slope of the Linear regression line?

6 * (FAVGCx.z - AVGCx.z) / (x - 1)

Why do you multiply by 6, and diivide by (x-1)

In detail I am using the formula to calculate the slope of the linear regression of the 5 period SMA of Price over three time horizons 5, 15, 40. This means that the formulas should be

6 * (FAVGC5.5 - AVGC5.5) / (5 - 1)

6 * (FAVGC5.15 - AVGC5.15) / (5 - 1)

6 * (FAVGC5.40 - AVGC5.40) / (5 - 1)

2) Is it possible to have the Random Walk Index RWI coded into the TC2000 platform?

Thank you very much for the support.

Kind regards.

It is just the way the math works out. If you are really interested in the math behind the formula template, check out bustermu's Tuesday, April 04, 2006 12:12:34 PM ET post in the Using Linear Regression vs Classical Peaks/Valleys for Divergence Analysis topic. It doesn't take you all the way there, but it gets you most of the way (just re-arrange the last term). I am not going to go through the entire derivation of the formula.

The 5 period linear regression slope of the 5 period SMA of price can be written as follows.

6 * (FAVG(AVGC5, 5) - AVG(AVGC5, 5) / (5 - 1)

The 15 period linear regression slope of the 5 period SMA of price can be written as follows.

6 * (FAVG(AVGC5, 15) - AVG(AVGC5, 15) / (15 - 1)

The 40 period linear regression slope of the 5 period SMA of price can be wrtitten as follows.

6 * (FAVG(AVGC5, 40) - AVG(AVGC5, 40) / (40 - 1)

The Random Walk Index (RWI) would appear to be a bit more complicated.

There have been some improvements to the Personal Criteria Formula Language since that post, but the syntax still requires significant manual expansion and I really don't have a generalized formula to provide.

Thank you very much Bruce, I will try to build the RWI. Do you think it could be done?

I can help you create formulas for other periods if you let me know what periods you want to use.

Hi Bruce, sorry for the late reply. You are very kind.

I would use the suggested time periods from Michael Poulos

-1 to 7 for the short term trend

-8 to 64 for the long term trend

Thanks

I am not providing formulas for 64 different periods. I am writing a formula for a 64 period version since it can be shortened to create any of the other formulas.

Since these periods fall directly in the middle of the short and long term periods given.

Thanks a lot Bruce, you are really really gentle,. :) :)

Hi Bruce,

Can you write a PCF that would give the slope of a line since a particular PCF event was true? 

For example, use the below PCF % true event:

ABS(ABS((L - AVGC21) / 5 / SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 - 21 * AVGC21 ^ 2) / 21) + .5) > .1) AND ABS(ABS((L1 - AVGC21.1) / 5 / SQR(ABS(C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 + C21 ^ 2 - 21 * AVGC21.1 ^ 2) / 21) + .5) <= .1)

Thanks in advance.

As a general rule, yes, but the practicality of doing so depends on the complexity of the condition. If we simplify the condition somewhat, we would come up with the following formula in TC2000 v18 for the linear regression slope since the condition was most recently true. The formula looks at the most recent 50 bars and returns a division by zero error if the condition was not true during the period.

IIF(XUP(ABS((L - AVGC21) / STDDEV21 + 2.5), .5), 0, IIF(XUP(ABS((L1 - AVGC21.1) / STDDEV21.1 + 2.5), .5), (C - C1) / 6, IIF(XUP(ABS((L2 - AVGC21.2) / STDDEV21.2 + 2.5), .5), FAVGC2 - AVGC2, IIF(XUP(ABS((L3 - AVGC21.3) / STDDEV21.3 + 2.5), .5), (FAVGC3 - AVGC3) / 2, 6 * IIF(XUP(ABS((L4 - AVGC21.4) / STDDEV21.4 + 2.5), .5), (FAVGC4 - AVGC4) / 3, IIF(XUP(ABS((L5 - AVGC21.5) / STDDEV21.5 + 2.5), .5), (FAVGC5 - AVGC5) / 4, IIF(XUP(ABS((L6 - AVGC21.6) / STDDEV21.6 + 2.5), .5), (FAVGC6 - AVGC6) / 5, IIF(XUP(ABS((L7 - AVGC21.7) / STDDEV21.7 + 2.5), .5), (FAVGC7 - AVGC7) / 6, IIF(XUP(ABS((L8 - AVGC21.8) / STDDEV21.8 + 2.5), .5), (FAVGC8 - AVGC8) / 7, IIF(XUP(ABS((L9 - AVGC21.9) / STDDEV21.9 + 2.5), .5), (FAVGC9 - AVGC9) / 8, IIF(XUP(ABS((L10 - AVGC21.10) / STDDEV21.10 + 2.5), .5), (FAVGC10 - AVGC10) / 9, IIF(XUP(ABS((L11 - AVGC21.11) / STDDEV21.11 + 2.5), .5), (FAVGC11 - AVGC11) / 10, IIF(XUP(ABS((L12 - AVGC21.12) / STDDEV21.12 + 2.5), .5), (FAVGC12 - AVGC12) / 11, IIF(XUP(ABS((L13 - AVGC21.13) / STDDEV21.13 + 2.5), .5), (FAVGC13 - AVGC13) / 12, IIF(XUP(ABS((L14 - AVGC21.14) / STDDEV21.14 + 2.5), .5), (FAVGC14 - AVGC14) / 13, IIF(XUP(ABS((L15 - AVGC21.15) / STDDEV21.15 + 2.5), .5), (FAVGC15 - AVGC15) / 14, IIF(XUP(ABS((L16 - AVGC21.16) / STDDEV21.16 + 2.5), .5), (FAVGC16 - AVGC16) / 15, IIF(XUP(ABS((L17 - AVGC21.17) / STDDEV21.17 + 2.5), .5), (FAVGC17 - AVGC17) / 16, IIF(XUP(ABS((L18 - AVGC21.18) / STDDEV21.18 + 2.5), .5), (FAVGC18 - AVGC18) / 17, IIF(XUP(ABS((L19 - AVGC21.19) / STDDEV21.19 + 2.5), .5), (FAVGC19 - AVGC19) / 18, IIF(XUP(ABS((L20 - AVGC21.20) / STDDEV21.20 + 2.5), .5), (FAVGC20 - AVGC20) / 19, IIF(XUP(ABS((L21 - AVGC21.21) / STDDEV21.21 + 2.5), .5), (FAVGC21 - AVGC21) / 20, IIF(XUP(ABS((L22 - AVGC21.22) / STDDEV21.22 + 2.5), .5), (FAVGC22 - AVGC22) / 21, IIF(XUP(ABS((L23 - AVGC21.23) / STDDEV21.23 + 2.5), .5), (FAVGC23 - AVGC23) / 22, IIF(XUP(ABS((L24 - AVGC21.24) / STDDEV21.24 + 2.5), .5), (FAVGC24 - AVGC24) / 23, IIF(XUP(ABS((L25 - AVGC21.25) / STDDEV21.25 + 2.5), .5), (FAVGC25 - AVGC25) / 24, IIF(XUP(ABS((L26 - AVGC21.26) / STDDEV21.26 + 2.5), .5), (FAVGC26 - AVGC26) / 25, IIF(XUP(ABS((L27 - AVGC21.27) / STDDEV21.27 + 2.5), .5), (FAVGC27 - AVGC27) / 26, IIF(XUP(ABS((L28 - AVGC21.28) / STDDEV21.28 + 2.5), .5), (FAVGC28 - AVGC28) / 27, IIF(XUP(ABS((L29 - AVGC21.29) / STDDEV21.29 + 2.5), .5), (FAVGC29 - AVGC29) / 28, IIF(XUP(ABS((L30 - AVGC21.30) / STDDEV21.30 + 2.5), .5), (FAVGC30 - AVGC30) / 29, IIF(XUP(ABS((L31 - AVGC21.31) / STDDEV21.31 + 2.5), .5), (FAVGC31 - AVGC31) / 30, IIF(XUP(ABS((L32 - AVGC21.32) / STDDEV21.32 + 2.5), .5), (FAVGC32 - AVGC32) / 31, IIF(XUP(ABS((L33 - AVGC21.33) / STDDEV21.33 + 2.5), .5), (FAVGC33 - AVGC33) / 32, IIF(XUP(ABS((L34 - AVGC21.34) / STDDEV21.34 + 2.5), .5), (FAVGC34 - AVGC34) / 33, IIF(XUP(ABS((L35 - AVGC21.35) / STDDEV21.35 + 2.5), .5), (FAVGC35 - AVGC35) / 34, IIF(XUP(ABS((L36 - AVGC21.36) / STDDEV21.36 + 2.5), .5), (FAVGC36 - AVGC36) / 35, IIF(XUP(ABS((L37 - AVGC21.37) / STDDEV21.37 + 2.5), .5), (FAVGC37 - AVGC37) / 36, IIF(XUP(ABS((L38 - AVGC21.38) / STDDEV21.38 + 2.5), .5), (FAVGC38 - AVGC38) / 37, IIF(XUP(ABS((L39 - AVGC21.39) / STDDEV21.39 + 2.5), .5), (FAVGC39 - AVGC39) / 38, IIF(XUP(ABS((L40 - AVGC21.40) / STDDEV21.40 + 2.5), .5), (FAVGC40 - AVGC40) / 39, IIF(XUP(ABS((L41 - AVGC21.41) / STDDEV21.41 + 2.5), .5), (FAVGC41 - AVGC41) / 40, IIF(XUP(ABS((L42 - AVGC21.42) / STDDEV21.42 + 2.5), .5), (FAVGC42 - AVGC42) / 41, IIF(XUP(ABS((L43 - AVGC21.43) / STDDEV21.43 + 2.5), .5), (FAVGC43 - AVGC43) / 42, IIF(XUP(ABS((L44 - AVGC21.44) / STDDEV21.44 + 2.5), .5), (FAVGC44 - AVGC44) / 43, IIF(XUP(ABS((L45 - AVGC21.45) / STDDEV21.45 + 2.5), .5), (FAVGC45 - AVGC45) / 44, IIF(XUP(ABS((L46 - AVGC21.46) / STDDEV21.46 + 2.5), .5), (FAVGC46 - AVGC46) / 45, IIF(XUP(ABS((L47 - AVGC21.47) / STDDEV21.47 + 2.5), .5), (FAVGC47 - AVGC47) / 46, IIF(XUP(ABS((L48 - AVGC21.48) / STDDEV21.48 + 2.5), .5), (FAVGC48 - AVGC48) / 47, IIF(XUP(ABS((L49 - AVGC21.49) / STDDEV21.49 + 2.5), .5), (FAVGC49 - AVGC49) / 48, 1 / 0))))))))))))))))))))))))))))))))))))))))))))))))))

Thanks Bruce. This works fine.

I got another question, using the new PCF lanuage in v18 is there an eaiser way to write PCF that will tell you the price percent change since a PCF % event was true?

If so, can you wrie one for this event?

L<L1 AND C>L1 AND WSTOC12.3<10 AND (100 * SUM(IIF(H + L + C > H1 + L1 + C1, (H + L + C) * V, 0), 12) / SUM((H + L + C) * V, 12) < 30)

Thanks

Maybe a little bit, but not a lot. Instead of nesting the following.

ABS(true condition) * (value if true) + ABS(false condition) * (next iteration of formula)

You can write it as:

IIF(true condition, value if true, next iteration of formula)

What really would be nice is something more like the following (this is specifically the percent change since true and doesn't work).

100 * (C / C(SinceTrue(true condition, 39)) - 1)

The way we end up having to write this currently is as follows.

100 * (C / IIF(L < L1 AND L1 < C AND WSTOC12.3 < 10 AND 100 * SUM(IIF(H + L + C > H1 + L1 + C1, (H + L + C) * V, 0), 12) / SUM((H + L + C) * V, 12) < 30, C, IIF(L1 < L2 AND L2 < C1 AND WSTOC12.3.1 <

Understood..that's the PCF enhancement i'm waiting for.

If i can PLEASE trouble you to do the same with one more PCF % true event (then i'll won't bother you for the rest of the day - i promise).

You'll definitely need to shorten this PCF % true event (because its way too long) and just give me the price percent change for up to 5 bars since this event (or what ever you can do would be apreciated), i'll catch the pattern and figure out how to extend the number of bars.

If it's too long to post, can you send it to me via TCMail?

Thanks in advance.

PCF % True event:

The shortend formula is just the following.

XUP(AVG((O + H + L + C) * V, 3) / AVGV3 + AVG((O + H + L + C) * V, 5) / AVGV5 + AVG((O + H + L + C) * V, 8) / AVGV8 + AVG((O + H + L + C) * V, 10) / AVGV10 + AVG((O + H + L + C) * V, 12) / AVGV12, AVG((O + H + L + C) * V, 30) / AVGV30 + AVG((O + H + L + C) * V, 35) / AVGV35 + AVG((O + H + L + C) * V, 40) / AVGV40 + AVG((O + H + L + C) * V, 45) / AVGV45 + AVG((O + H + L + C) * V, 50) / AVGV50)

The percent change since true for the most recent four bars can be written as follows.

100 * (C / IIF(XUP(AVG((O + H + L + C) * V, 3) / AVGV3 + AVG((O + H + L + C) * V, 5) / AVGV5 + AVG((O + H + L + C) * V, 8) / AVGV8 + AVG((O + H + L + C) * V, 10) / AVGV10 + AVG((O + H + L + C) * V, 12) / AVGV12, AVG((O + H + L + C) * V, 30) / AVGV30 + AVG((O + H + L + C) * V, 35) / AVGV35 + AVG((O + H + L + C) * V, 40) / AVGV40 + AVG((O + H + L + C) * V, 45) / AVGV45 + AVG((O + H + L + C) * V, 50) / AVGV50), C, IIF(XUP(AVG((O1 + H1 + L1 + C1) * V1, 3) / AVGV3.1 + AVG((O1 + H1 + L1 + C1) * V1, 5) / AVGV5.1 + AVG((O1 + H1 + L1 + C1) * V1, 8) / AVGV8.1 + AVG((O1 + H1 + L1 + C1) * V1, 10) / AVGV10.1 + AVG((O1 + H1 + L1 + C1) * V1, 12) / AVGV12.1, AVG((O1 + H1 + L1 + C1) * V1, 30) / AVGV30.1 + AVG((O1 + H1 + L1 + C1) * V1, 35) / AVGV35.1 + AVG((O1 + H1 + L1 + C1) * V1, 40) / AVGV40.1 + AVG((O1 + H1 + L1 + C1) * V1, 45) / AVGV45.1 + AVG((O1 + H1 + L1 + C1) * V1, 50) / AVGV50.1), C1, IIF(XUP(AVG((O2 + H2 + L2 + C2) * V2, 3) / AVGV3.2 + AVG((O2 + H2 + L2 + C2) * V2, 5) / AVGV5.2 + AVG((O2 + H2 + L2 + C2) * V2, 8) / AVGV8.2 + AVG((O2 + H2 + L2 + C2) * V2, 10) / AVGV10.2 + AVG((O2 + H2 + L2 + C2) * V2, 12) / AVGV12.2, AVG((O2 + H2 + L2 + C2) * V2, 30) / AVGV30.2 + AVG((O2 + H2 + L2 + C2) * V2, 35) / AVGV35.2 + AVG((O2 + H2 + L2 + C2) * V2, 40) / AVGV40.2 + AVG((O2 + H2 + L2 + C2) * V2, 45) / AVGV45.2 + AVG((O2 + H2 + L2 + C2) * V2, 50) / AVGV50.2), C2, IIF(XUP(AVG((O3 + H3 + L3 + C3) * V3, 3) / AVGV3.3 + AVG((O3 + H3 + L3 + C3) * V3, 5) / AVGV5.3 + AVG((O3 + H3 + L3 + C3) * V3, 8) / AVGV8.3 + AVG((O3 + H3 + L3 + C3) * V3, 10) / AVGV10.3 + AVG((O3 + H3 + L3 + C3) * V3, 12) / AVGV12.3, AVG((O3 + H3 + L3 + C3) * V3, 30) / AVGV30.3 + AVG((O3 + H3 + L3 + C3) * V3, 35) / AVGV35.3 + AVG((O3 + H3 + L3 + C3) * V3, 40) / AVGV40.3 + AVG((O3 + H3 + L3 + C3) * V3, 45) / AVGV45.3 + AVG((O3 + H3 + L3 + C3) * V3, 50) / AVGV50.3), C3, 1 / 0)))) - 1)

Hi Bruce,

First of all, thanks for all your help. Can you write a PCF that will tell me the price percent change on the below PCF % True event? up to 20 bars if possible.

L<L1 AND H>L1

Thanks in advance.

Please try the following indicator formula.

100 * (C / IIF(L < L1 AND L1 < H, C, IIF(L1 < L2 AND L2 < H1, C1, IIF(L2 < L3 AND L3 < H2, C2, IIF(L3 < L4 AND L4 < H3, C3, IIF(L4 < L5 AND L5 < H4, C4, IIF(L5 < L6 AND L6 < H5, C5, IIF(L6 < L7 AND L7 < H6, C6, IIF(L7 < L8 AND L8 < H7, C7, IIF(L8 < L9 AND L9 < H8, C8, IIF(L9 < L10 AND L10 < H9, C9, IIF(L10 < L11 AND L11 < H10, C10, IIF(L11 < L12 AND L12 < H11, C11, IIF(L12 < L13 AND L13 < H12, C12, IIF(L13 < L14 AND L14 < H13, C13, IIF(L14 < L15 AND L15 < H14, C14, IIF(L15 < L16 AND L16 < H15, C15, IIF(L16 < L17 AND L17 < H16, C16, IIF(L17 < L18 AND L18 < H17, C17, IIF(L18 < L19 AND L19 < H18, C18, IIF(L19 < L20 AND L20 < H19, C19, IIF(L20 < L21 AND L21 < H20, C20, 1 / 0))))))))))))))))))))) - 1)
