Alright I will had more variable functions to this later but if a few helpfull souls would help debugging/testing it that would be great. 1) Variable Reference Function Here is the syntax : ExtFml("ForumDll.VarRef",Data Array, LoopBack period) For Example: ExtFml("ForumDll.VarRef",O,C) Here I assume Negative close, I will always look back not forward ... 2) Variable HHV Function Here is the syntax : ExtFml("ForumDll.VarHHV",Data Array,periods) For Example: ExtFml("ForumDll.VarHHV",O,C) 3) Variable LLV Function Here is the syntax : ExtFml("ForumDll.VarLLV",Data Array,periods) For Example: ExtFml("ForumDll.VarLLV",O,C) 4) Variable SUM Function Here is the syntax : ExtFml("ForumDll.VarSUM",Data Array,periods) For Example: ExtFml("ForumDll.VarSUM",O,C) 5) Variable HHVBARS Function Here is the syntax : ExtFml("ForumDll.VarHHVBARS",Data Array,periods) For Example: ExtFml("ForumDll.VarHHVBARS",O,C) 6) Variable LLVBARS Function Here is the syntax : ExtFml("ForumDll.VarLLVBARS",Data Array,periods) For Example: ExtFml("ForumDll.VarLLVBARS",O,C) 7) Variable Moving Average Function Here is the syntax : ExtFml("ForumDll.VarMOV",Data Array,periods,Method) For Example: ExtFml("ForumDll.VarLLVBARS",O,C,S) Method available are : Exponential E Simple S Triangle T Weighted W Let me know what you think ---Edited on August 5 th 2005 ---- ---Edited on August 6 th 2005 ---- Added SumVar Function Cleaned up source code and added some error traps. ---Edited on August 6 th 2005 - later that day :D ---- Added VarHHVBARS and VarLLVBARS ---Edited on August 8 th 2005 added Variable Moving average function ---Edited on August 12 th 2005 added Variable RSI, Variable MO, Variable CMO functions Patrick :mrgreen:

hey h I just added a baby step :D honestly the dev kit looks tough to use but I think its because the manual that comes with it is not very good ( :oops: I might get in trouble for that one ) ... Once you get the logic it becomes pretty easy to use and manipulate. Patrick :mrgreen:

Okay gave this puppy a spin. Worked very well. Here's an adaptive indicator using an RSI A:=RSI(14); ExtFml( "ForumDll.VarSUM",C,A)/A I seem to remember g_ showing someone different ways to write a moving average, some using the sum function. This uses one of those ideas to create a simple moving average that changes its lookback based on the value of a RSI(14). Preston

Added Variable moving average function. Let me know if there are other variable indicators you think would be usefull. As always I really need people to test this. Thanks Patrick :mrgreen:

Thanks Preston :D Would you mind posting it on your board for me? Patrick :mrgreen:

Patrick, Just tried the sum dll in the same formula and now I'm getting a division error. preston

Patrick, Tried the formula again today and it worked fine...must have been a glitch on my side. I did notice a big difference on the indicators with the MA being much smoother. As far as adding more functions to the MA , variable and volume would seem to be the most useful but the 4 you have is fine. Preston

Thanks for the formula that looks interresting, I hope you will keep them coming :D

Patrick, I'd like to code one more indicator using the idea behind the DMI and end up with something similar to the Jurik DMX which is just a low lag DMI. In order to do that I need a variable RSI DLL. Can you do that? Thanks, Preston
