"Price Oscillator(3,10,16) -> obviously similar to a MACD"
------------------------------------------------------------
alf44,
Is this the PPO calculation via Quotetracker? I don't see anything comparable on SF. The SF APO, PPO and DPO only accept two parameters.
Thank you

No !
It's not quite the same calculation.
Typically, a MACD is the difference between 2 Exponential MAs [say a EMA(3) minus an EMA(10)]...the "fast" line...then a 16 period EMA of that 3 minus 10 is calculated and used as the "slow" line of the MACD indicator ! The difference in the 2 EMAs is expressed in points.
The typical PPO is calculated much like the above MACD except that the difference between the 2 EMAs [(say a EMA(3) and an EMA(10)] is expressed in percentages.
But...basically the MACD and the PPO appear identical on a chart and are for all intents and purposes...identical indicators.
I always laugh when I go to message boards where some poster has posted a chart (something I wish we could do here at SF but can't) and he/she has the chart accompanied with no less than 15 indicators. Almost always there will be a PPO and a MACD of the same parameters. HELLO ! Why do you need 2 "identical" indicators...and...why do you need 15 indicators in the first place ? But I digress !
Now...back to the other part of your question...the APO and the DPO ! To be honest I have not tried either of these. The APO does appear to be similar to what I use but as I have never played around with it I'm just not sure.
I just wrote MY OWN criteria to create "MY Oscillator" !
The 3/10/16 Price Oscillator I use in my SF filters is calculated as follows:
-------------------------------------
set{myOSC, MA(3) - MA(10)}
set{myOSCtrend, CMA(myOSC,16)}
and...to draw it on an SF chart you will need this:
draw myOSC
draw myOSC line at 0
draw CMA(myOSC,16)
-------------------------------------
Here's a simple filter for illustrative purposes only to show the 3/10/16 Oscillator:
--------------------------------------
As you may notice I am using Simple MAs instead of Exponential MAs in the calculation. That is the ONLY difference in this "3/10/16 Price Oscillator" and a standard "3/10/16 MACD" !!!
Bottom line...there's not a hellava lot of difference. A standard MACD will work just fine...and in the case of QuoteTracker (which you mentioned) I use a 3/10/16 MACD because I'm not able to designate the Moving Averages "Simple" ! I'm forced to use "Exponential" Moving Averages.

It's not your oscillator. It's Linda Raschke's oscillator from "street smarts". Give credit where credit is due.

alf44,
Thank you for the thorough explanation and examples. It was very helpful and saved me hours of LBR etc. research. I appreciate the contribution and the willing sharing your trading strategy.
Sincerely,
SS

I label it "my oscillator" because it is in "my filters"...and the StockFetcher set statements used to define it were written by ME !
I certainly didn't "invent" it !
For the record, it ain't Rashke's oscillator either !
The 3/10 Price Oscillator has been around for a hundred years...and was around LONG before "Street Smarts" !
Also, much of what LBR does herself...she adapted from George Douglas Taylor's 3 day cycle stuff and Toby Crabel's (NR4s/NR7s etc...) Range Contraction/Expansion stuff !
"poindexter"...if you go back and read my posts you will notice that most of what I try to do is based on LBR's work. My Range Contraction/Range Expansion filter was inspired by LBRs work. I have repeatedly given her credit and have even said here in these forums that LBR is the closest thing to a "trading mentor" I have. I have been following LBR since the early 90s and have tried to read everything she has ever written...INCLUDING..."Street Smarts" !
