It is an attempt to list different MA know here and there feature/quality/etc... For now we got : - FIR : weighted MA (classic original MA with all weigths to one, triangular, etc...) - All classic IIR : EMA/DEMA/TEMA - The John Ehler's MA : Median Filter, Median-MA Difference Filter, Ehlers Filter, MAMA, FRAMA, Laguerre Filter adaptive or not adaptive - Others : T3, Jurik MA, Alan Hull's MA, KAMA, VIDYA As we are on MA, i just posted to the library an AFL a few days ago for Laguerre Adpative Filter from John Ehler's. Herman, i don't know Alan Hull's MA. I search it on the AFL list with "Alan Hull", "Allan" or "Hull" keywords... but return me nothing. Can you post the link please. Is it useful ? How based on your experience ? Thanks. It make me think that maybe if we can have the search option with the add option to search through the AFL code too and the people's remarks, will be more powerfull... this way we can find some code, or any remarks about a keyword... etc. I think this library is one of the powerfull thing for Amibroker so it can be more good with such search option. And maybe add the same but for script in VBS, Java (script or not) or C(++), etc..., so people can post utility function VBS or others that can greatly speed up creation of new AFL indicators containing script part.

Both are available in afl. Before buying and expensive formula you might want to try find a formula-owner who is willing to test it in "your" formula for you. Not all systems benefit from using a minimum lag indicator.
