Hmmm... tricky stuff, Patrick. How about replicating the LastValue(variable+PREV-PREV) trick using C++ loops to replace the two PREV functions - would that work? jose '-)

Finally found a way to get rid of +prev-prev :D I will test some more and post the dll and instructions later. Patrick :mrgreen:

Jose, I goofed up and I'm working to fix it ... Worse case scenario, why don't you tell me which functions you really need to be variable ... I have been busy, my hard drive had to be reformated etc ... :( So you will to be patient, but I will get there ultimately. Patrick :mrgreen:

Hi, As I'm only getting back to the MetaStock plugins development, I'm no more an expert in that field (so the following statements shouldn't be taken for law). But I think that a Dll function that returns a constant value is impossible as Dll functions return a MSXDataInfoRec pointer which is basically a structure containing an array of float values... So the only way to get that done is to use a Dll providing directly indicators that allow a variable period in input, as the one I developped... Just my two cents, Patrick (aka Nag)

Ah, When I started working on MY set of adaptive indicators (http://thedml.com/pages/products/asi.html) about a year ago, I didn't know of anyone else with adaptive indicators. Now I know of three. :? Needless to say, I hoped to sell these indicators since I thought they were the only ones available....and I still think that I have found some novel applications of them that have been somewhat overlooked. Just a couple comments on the development of the indicators: I agree with Nag, I think it is impossible to find a workaround that will solve the problem of a constant input. That's all I can say, and I thought about it for a long time. Finally, I am still hoping to sell my set on indicators...a basic set will cost around $80-$100. This set will include around 10 "building block" indicators. An entire set of around 40 will cost maybe around $180. At first glance, you may turn these down in favor of some free ones, and I can't blame anyone for that. However, being designed to be sold for profit as a professional product, they do have some advantages. 1.) The first set comes with a 30 plus page manual, the other, which is packaged with an Ehlers' Indicator set, comes with an approx. 60 page manual. The manuals contain specific examples of how to use the indicators for several very specific purpose, including loops. 2.) They have been tested very rigorously, and they match there metastock counterparts exactly. 3.) They have been optimized with a specific algorithm. When comparted to the easy or most intuitive algorithm (which I'm not sure if Nag or patrick have used) the optimized algorithm calculates the results about an order of magnitude (10 times) as fast. The technique is known as a "sliding window" algorithm. 4.) It is also going to contain a handful of formula building tools that the MS community has been asking for for a while. So once again, I can't blame anyone for taking any certain action with their own work, but I should be offering the deal above through my site in the next week or two. Just have to get the new product information up there, and I haven't had time to get around to changing the site. I wish I could have waited until I had the new site up, but oh well. Finally, I hope you look into our ADSI toolkit...The next release of it should be very soon, and it will contain more high level tools like expert advisors and systems based on the ADSI indicators. Our new site is also going to have a forum very similar to this one specifically for discussing adaptive indicators and their applications, including ADSI. Good luck in your coding, Brad Ulrich The Dynamic Market Lab, LLC www.thedml.com

Wrong!!!!!

You're are professional as it comes. Why wouldn't you be? Because you don't make a living selling proprietary products for your own corporation? P L E A S E! Indeed, you write formula's for the most popular technical software sold... not to get rich, but to help others learn. You are a team player by design and a damn good one. Stop the self-debasing junk... you're a professional! :wink: p.s. I'll wait for the free version to come out. Who needs the manual when you can get the designer live on the forum?! Heck, I'll write the FAQ for you! LOL!

Thanks, Patrick (aka Nag). However, I would have thought that if LastValue(variable+PREV-PREV) works in MetaStock to convert variables to static values, perhaps that same MS trick could be replicated by using loops within the dll to replace the two PREV functions - similar to AmiBroker's (much faster) loop function replacing MetaStock's PREV function. I don't know... this variable to static problem "smells" like it should have a solution... jose '-) http://metastocktools.com/#metastock

You may be right there, However, I think that this would not be possible with the Developer's Kit as is stands now....The PREV functions are not passed into the DLL in any way. I have always seen the +PREV-PREV trick as basically be a special case for the Metastock formula parser. This process happens internally in Metastock. However, for someone like Patrick with access to the source, it may not be... this is all pretty hairy stuff though :lol: Brad

Sorry, Patrick, but I don't think that I will release my Dll freely to the public, as it's been quite a long time to develop and test... but you'll see that by yourself for sure :wink: But I plan to update it, in order to provide an adaptative version of any indicator in MS that comes with a fixed period. And I guess that it'll be available for a few tens of $. Those indicators, as you stated, are perhaps not worth much, but they still answer a need that MS hasn't be able to address for a long time (as I coded my Dll in 2001 :shock: that long ? :) ). At the moment, I'm building a website to present my work, as I have some other plugins that might interest the community of MS users/developers. Patrick (the other one aka Nag :wink: )
