RE: [RT] Digest Number 647

["John Hall" <jrhall@xxxxxxxxxxxx>]

Terry,
The Adaptive Stochastic code listed in your email was originally based on
Tushar Chande's indicator but in it's present form is very different.  This
version uses DSP techniques where Chandes uses a standard deviation function
to change the length and had set limits.  The current version uses the
Hilbert transform to determine length and is not limited in length high or
low.  Chande's version was not smoothed.

Here's the Chande code for you to compare.

Regards;
John

{TRADESTATION CODE FOR ADAPTIVE STOCHASTIC OSCILLATOR}
{--- (c) 2K Tushar Chande; Adaptive Stochastic Oscillator ---}

	vars: v1(0), v2(0), v3(0), v4(0) ;
	vars: lenmax(28), lenmin(7), currlen(0) ;
	vars: hh(0), ll(0), stoch(0), stochma(0) ;

{--- Calculate 20-day std. Dev. And its 20-day range ---}

	v1 = stddev(c,20) ;
	v2 = highest(v1, 20) ;
	v3 = lowest(v1, 20) ;

{--- Create v4: stochastic oscillator for 20-day std. dev. ---}
{--- if v1=v2 (highest level) => v4 = 1; if v1=v3 (lowest level) =>
v4=0 ---}

	if (v2-v3) > 0 then v4 = ((v1 - v3)/(v2-v3)) Else v4 = 0 ;

{--- Calculate current effective length; if v4 = 1, then length =
mininum ---}

	currlen = IntPortion(lenmin + (lenmax-lenmin)*(1-v4)) ;

{--- Calculate stochastic oscillator and its 3-day exponential average ---}

	hh = highest(h, currlen) ;
	ll = lowest(l, currlen) ;
	if (hh-ll) > 0 then stoch = ((close - ll)/(hh - ll)) * 100 ;
	if currentbar = 1 then stochma = 0 else
		stochma = 0.5*stoch + 0.5*stochma[1] ;

{--- Plot data ---}

	plot1(stoch, "adapt_stoch") ;
	plot2(stochma, "stochma") ;
	plot3(80, "hi_ref") ;
	plot4(20, "lo_ref") ;

{ --- End of code -}

For some time I have been trying to find background explanation on Chande's
adaptive stochastic. Can't find it presented in TASC. Was it first
introduced in either of his books: The New Technical Trader or Beyond
Technical Analysis?

Amazon.com's reprint of the index from New Technical Trader doesn't list
the adaptive stochastic.

Any guidance to his original presentation would be appreciated.

I would also appreciate anyone's thoughts on either of Chande's two books.
Are they worth buying? His past articles in TASC were terse, IMO. More meat
than fluff. Do the books follow through?
