Andy,
The EMA coding I am referring to is in the April 2004 Traders
Tips section of Technical Analysis of Stocks and Commodities
(TASC).
Called "PiecewiseEMA", it restarts the lookback of an EMA-type
calculation every time there is a trigger of an event.
See the complete code in the Members section under
Stocks and Commodities Traders' Tips April 2004.
Something that I did (and still do) when I first migrated to
AB, was to code my version of the articles in TASC then check my code against
the code that TJ would provide for the magazine in the Traders Tips section of
the magazine. Seeing how the Master codes stuff vs. how I would, was both
illuminating and humbling. Didn't matter if I really had no interest in the
article, TJ would occasionally put in a method I hadn't considered.
BTW: Thanks to Tomasz for updated list. (Please feel free to
add more at your pleasure :-)

indicators / variable periods
Tomasz,
I should
definitely have experimented more with the various functions before I posted
my question, but perhaps the user’s guide needs updating to point out the
(IMO) extremely useful dynamic nature of the functions that Corey has
highlighted?
Corey,
Thanks
very much indeed for that post. My life, and full transition to AB, has just
been made sooo much easier!...I should now be able to construct just about any
dynamic variable-period indicator from those basic functions. And I couldn’t
agree more about your comments on the significance of these
features…
With
reference to EMA coding, I guess you mean that:
EMA(array,period)
is equivalent to AMA(array, 2/(period+1))
???
Regards
Andy
