Rick,
The biggest problem with the use of DLL's is making sure that you
have the right one installed and are referring to it. There were two
DLL's available at the Equis forum and now a third.
The difference between the first two, which are in the files here,
are the naming convention...in one you call:
ExtFml("ForumDLL.VarMOV",2*(Mov(C,period/2,W))
-Mov(C,period,W),Sqrt(period),W);{end}
in the other you would use:
ExtFml("Forum.VarMOV",2*(Mov(C,period/2,W))
-Mov(C,period,W),Sqrt(period),W);{end}
The only difference is whether you use Forum or ForumDLL.
If you are going to use variable inputs then a DLL is really the way
to go. There was a time when only a select few of us had them but
today there are any number of DLL's available and for free. The same
thing that you are going through is the reason they were designed.
If I were to use a LastValue indicator, I would want it to be as a
visual. I would always be skeptical of a trading system or signal
using it.
Thanks for the compliment! You're right we do learn from the
exercises. Truth is I'd really like to see more step up to the plate
and give coding a try. Its really not that difficult. In the end I
think you come away with some useful ideas and a much better
understanding of how an indicator works.
Best of luck,
Preston
