The PolyFit & GaussianElimination Functions use only the data you pass it ...
The Demo Main AFL was set up to use Beg & End Range markers but you can easily change those to whatever you like. The extrapolations are only calculated once the fit as of some bar has been done. If you click CHECK it will probably say that it does look forward but that is only because one the arrays is purposely down shifted so that extrapolation values can be calculated beyond the most current bar prior to plotting them shifted into the future ... It does not look forward at all. --- In [email protected], "Chris DePuy" <[EMAIL PROTECTED]> wrote: > > Fred, > Thank you for sharing. > To what extent does this code look forward, may i ask? > Chris > > ----- Original Message ----- > From: Fred Tonetti > To: [email protected] > Sent: Tuesday, October 03, 2006 3:29 PM > Subject: [amibroker] Polynomial Trendlines > > > There seemed to be some interest in this sort of thing the other day ... > > This one I can publish since it's not tied to any copyrighted material I am > aware of ... > > It will calculate a nth ( 1 - 8 ) Order Polynomial Fit of whatever data you > toss it using Gaussian Elimination for simultaneous solution of multiple > linear equations.
