Re: [amibroker] AB built-in stochastic vs. my own: the same code, different picture

["john gibb" <jgibb1@xxxxxxxxxxxxx>]

Hi BM,

This may not be a complete answer to your dilemma but, first of all, to
'obtain the same result' as your first example, I had to use this code:

range = Prefs( 14 );
_N( ranstr = "("+WriteVal( range, 1.0 )+")" );
Plot( StochK(range,3), "Stochastic %K"+ranstr, -8 );
Plot( StochD(range,3,3), "Stochastic %D"+ranstr, -9 );

instead of your second example below.

In doing that, with Amibroker 4.50.5, I was just explitly using the default
StochK and StochD values from the Help file. (to see these values, press F1
after putting the cursor within the function name in question.)

And I think the Stochastic settings in Preferences|Indicators apply only to
StochD.

-john
