Have been trying to put togeather a PCF for a Coppock indicator. Its my first try at PCF programming, with uncertian success. Any input or alternatives appreaciated.
Formula:
Calculate 294 day ROC (Price) for the index. Use monthly closing price.
Calculate 231 day ROC (Price) for the index. Use monthly closing price.
Add the results of 1 and 2.
Calculate a 210 day weighted moving average of the result.
My Frankenstien PCF
(C294 + C231) + (AVGC2.210)
I have tried a number of varitions on this theme with no real success.
Thank you in advance!

You might want to try this in TeleChart 2007 with SnapSheets. PCF's will probably become extinct as SnapSheets grows in usefulness. Plus, SnapSheets pretty much have limitless capability whereas PCF's are fairly limiting.

TyStik,
From what I have seen on the internet, your description should read:
Formula:
Calculate 14 bar ROC (Price) for the index. Use monthly (21 day) closing price.
Calculate 11 Bar ROC (Price) for the index. Use monthly (21 day) closing price.
Add the results of 1 and 2.
Calculate a 10 bar weighted moving average of the result.
Please notice that:
14*21 = 294
11*21 = 231
10*21 = 210
Do you concur?
If so, writing the PCF is a trivial matter.
Thanks,
Jim Murphy

Addendum:
Plotting the Coppock Indicator is even easier than writing the PCF.
Thanks,

TyStick,
If bustermu's post above seems accurate, let me know and I will write the PCF for you (and show you how to plot this as well)

Thanx bustermu and Craig S for your input. Im sure that this is a "no brainer" for you both. With more practice Im sure I'll pick up the syntax soon enough. I'll give the above mentioned formula a try and get back to you.

LOL... OK...Here are the results of about 2 hours worth of experamentation.
(O14 * 21 = 294) + (O11 * 21 = 231) + 10 * 21 = 210
I know its nowhere close to what Im trying to accomplish, but Im an old school, learn-by-your-mistakes, student. Luckly I have more time than common sense... I dont want an easy answer...but I would be very grateful for clue or hint in the right direction.
Thanx!

Lets focus a bit.
Do you want to tackle plotting this first or a PCF for it first?
Clue: To plot this we must be on a monthly (21-day) chart.
Clue: For the PCF we have to use daily data. Here are some things to look at.
When on a monthly chart:
Recent Bar
Close= C
Open= O20
High=MAXH21
Low=MINL21
Previous Bar
Close=C21
Open=O41
High=MAXH21.21
Low=MINL21.21
I will stay with you through your process. Let me know what I can give to help.

This is a GREAT lead to follow. I really was just seeking a clue in the right direction to construct the PCF. I'll go back and torture the syntax some more.
Once again, Thank you for your quick responce Craig!

I love that you are trying to learn this vs. having me spit out the answer. It shows a desire to understand which I, as a trainer, don't see enough of.
You let me know anything you need next.

Trying to build the indicator without success...found this thread. Did anyone succeeded in creating the PCF? Need help. Thanks!

Craig,
"PCF's will probably become extinct as SnapSheets grows in usefulness.
RJMGroup"
Is the above statement true? I have all my indicators set up in Telecharts, just the way I want them (I am making money), so I am not interested in snapsheets or any other program. Telecharts is all that I need!
Will you keep Telecharts in the future or will it be phased out in favor of snapsheets?
Thanks,

amberpax,
There are no plans to phase out TeleChart. That said, there are a lot of things that can be done with Blocks Player that can't be done using TeleChart's Personal Criteria Formula Language.
link,
You may wish to try one of the following:
Based on ROC (Net Change):
(10 * (2 * C - C294 - C231) + 9 * (2 * C21 - C315 - C252) + 8 * (2 * C42 - C336 - C273) + 7 * (2 * C63 - C357 - C294) + 6 * (2 * C84 - C378 - C315) + 5 * (2 * C105 - C399 - C336) + 4 * (2 * C126 - C420 - C357) + 3 * (2 * C147 - C441 - C378) + 2 * (2 * C168 - C462 - C399) + 2 * C189 - C483 - C420) / 55
Based on ROC (Percent Change):
100 * (10 * (C / C294 + C / C231) + 9 * (C21 / C315 + C21 / C252) + 8 * (C42 / C336 + C42 / C273) + 7 * (C63 / C357 + C63 / C294) + 6 * (C84 / C378 + C84 / C315) + 5 * (C105 / C399 + C105 / C336) + 4 * (C126 / C420 + C126 / C357) + 3 * (C147 / C441 + C147 / C378) + 2 * (C168 / C462 + C168 / C399) + C189 / C483 + C189 / C420) / 55 - 200

Chris Worden has explicitly said that TeleChart will continue to be developed and supported. TeleChart is in no way being replaced by the Tools for the Blocks Player.

Thanks Bruce.
The indicator appearance is different from what I see in the book. It there anyway to put the indicator swing between "100" and "-100", with "0" as the central line? Need a constant movement band. Thanks!

TeleChart's Custom Indicators normally use auto-scaling. There is no way to automatically fix the scale other than to use the Price Scale (which is not appropriate in this case). One option that will get you closer to what you want would be to check Center Zero Line.
To plot a Monthly Indicator on a Daily chart:
Select Chart Template | Add Indicator | Indicator:
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: 100 * (10 * (C / C294 + C / C231) + 9 * (C21 / C315 + C21 / C252) + 8 * (C42 / C336 + C42 / C273) + 7 * (C63 / C357 + C63 / C294) + 6 * (C84 / C378 + C84 / C315) + 5 * (C105 / C399 + C105 / C336) + 4 * (C126 / C420 + C126 / C357) + 3 * (C147 / C441 + C147 / C378) + 2 * (C168 / C462 + C168 / C399) + C189 / C483 + C189 / C420) / 55 - 200
On a Monthly chart:
Select Chart Template | Add Indicator | Indicator:
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: 100 * (10 * (C / C14 + C / C11) + 9 * (C1 / C15 + C1 / C12) + 8 * (C2 / C16 + C2 / C13) + 7 * (C3 / C17 + C3 / C14) + 6 * (C4 / C18 + C4 / C15) + 5 * (C5 / C19 + C5 / C16) + 4 * (C6 / C20 + C6 / C17) + 3 * (C7 / C21 + C7 / C18) + 2 * (C8 / C22 + C8 / C19) + C9 / C23 + C9 / C20) / 55 - 200

What does the 'ROC' stand for in the text below? I copied it from one of the posts above. Thanks.
TyStik,
From what I have seen on the internet, your description should read:
Formula:
Calculate 14 bar ROC (Price) for the index. Use monthly (21 day) closing price.
Calculate 11 Bar ROC (Price) for the index. Use monthly (21 day) closing price.
Add the results of 1 and 2.
Calculate a 10 bar weighted moving average of the result.
