@graftonian,
I'm not familiar with the Schaff Trend Cycle and there seems to be little reliable information about it on the web; do you implement it in an SF filter, and if so what conditions need to be met?
Thanks,
Ed S.

Kevin did some experimenting with the Schaff trend cycle (STC) however I do not think it is possible in SF.
It is available in TOS

This is what I started on a few months ago, it is incomplete,
/*First, the 23-period and the 50-period EMA and the MACD values are calculated:*/
set{EMA1, EMA(23)}
set{EMA2, EMA(50)}
set{var1, EMA1 - EMA2}
/***Second, the 10-period Stochastic from the MACD values is calculated:
%K (var1) = %KV (var1, 10);
%D (var1) = %DV (var1, 10);
Schaff = 100 x (var1 - %K (var1)) / (%D (var1) - %K (var1)).***/

I found a link to the PDF that the creator of the Schaff Trend Cycle, Doug Schaff, authored in 2008 when he released his indicator for public use.
https://www.omnitrader.com/currentclients/proforum/get-attachment.asp?attachmentid=2503
It contains background on him and the reasons for the indicator, calculation details and example charts on how to use it, about 20 page read.
Now for some filter experimentation....,
Ed S.

I do not believe that Kevins work is valid (I never thought I'd say that!)
If one compares Kevins version of STC with that found on TOS, there is a considerable lag.
Today, FNSR triggered on TOS, waiting for SF. The last TOS trigger was Aug 6, while SF trigger occurred on Aug 10.
Back in 2010, said: " ..... However, to make it better, one should be using an adaptive cycle period - unfortunately, SF code does not allow for the use of a variable in these types of calculations. If it did, this could be much more useful. Oh well. "

@ graftonian,
It appears KofG used a cycle length of 20 instead of the normal default of 10.
if we change the 20's to 10's in his filter FNSR triggers on SF on Aug8th instead of Aug10th.
Further down he is using an Custom ema of 5 for some reason and if we remove that and just use his Var4 as the signal it improves to triggering on FNSR on Aug 7th.
I looked at 2 other chart platforms and downloaded a trial paper trading copy of Think or Swim and none of the 3 show a trigger on FNSR for yesterday.
All 3 have the same values for the Aug 6th trigger on FNSR.
The settings for the Schaff Trend Cycle in my version of TOS are 23,50,10,3,75,25, exponential.
Are those your settings also?
Thanks,
Ed S.

You are correct, I was looking at the 1 hour chart. Oops

@graftonian,
I believe this is an accurate Schaff Trend Cycle filter:

Ed, I put this thread on the back burner when I got interested in options trading. Now, with the interest in the Weinstein book, there seems to be a place for this. The STC calculated agrees with those calculated in Tastytrade. I do have a question. Why can't I use statements such as "draw STClong line at 20" or "STClong approaching 20 from below" et al? Are you enjoying your autographed copy of Stans book?
