I did code from both books a while back ... not satisfied that they work well enough to be useful. Not sure I even have his code any longer.
Notice that he does not use any of those principals in his codes. The codes described assume cyclicity and while they work when cycles are well defined, he himself states that useful cycles exist only about 15% of the time. To answer your question directly, his later work is more efficient (needs less CPU time) because of the median filter he uses. I like his older code better, but neither was very useful. ----- Original Message ----- From: Soham Das To: [email protected] Sent: Friday, October 09, 2009 8:51 AM Subject: [amibroker] Ehler, Calculations and Others Hello Everybody, Has anyone here, implemented Ehler's numerous tools and indicators which he has discussed thoroughly in his books. Of course I did come across, a few AFLs (implementing Ehler's work )before, but I intended to touch up a slightly different point. Did anyone notice, that his calculations of simple tools like Sinewave Indicator or Dominant Cycle finder etc, have different implementations in his two books, namely Rocket Science for Traders and Cybernetic Strategies for Stocks and Futures. I have tried implementing his work after reading RSforT but I couldnt make it work.Has anyone else faced it? Or am I muddling up somewhere? I haven't read CSforSF , which I guess is his latest offering, so to those who have read it, has he explained his reasons for changing the implementation? Looking forward to some help Soham ------------------------------------------------------------------------------ Yahoo! India has a new look. Take a sneak peek.
