Hello everybody!
I am a newbie to metastock so I need help on its programming language.
The formula is as follows,
LC:= llvbars(C,21); {Lowest period of the close since 21 days}
Low1:= ref(MACD(),(-1*LC));
The above formula doesnt seem to work.
Error message is "This variable or expression must contain only constant data."
I think it refers to variable LC, which returns only one number...
What I want to do is get the value of the MACD during the lowest close of the last 21 days.
Can anybody explain this or tell me whats wrong in this formula?
Can anybody show me a better way?
Thank you in advance.
Zaldy

HI Zaldy;
you can use the function
ExtFml( "Forum20.LLVBARS", Data Array, Variable Period).
but after that you do to download forum20.dll from the site and to make it in
C:\Program Files (x86)\Equis\MetaStock\External Function DLLs and it will work.

Hello ClaudeBrunet,
Thank you for your reply. It was very fruitful.
Now I understand why my formula doesnt work,
metastock does not allow variables to be declared as constants..
I have already downloaded the dll file, together with its documentation.
And currenty reading it...
Since Im a newbie, my head is spinning right now... hahaha
Again, thank you very much.
Best regards,
Zaldy

Hello there again,
Can the ExtFml("blah blah blah".... can be used in the expert advisor?
Best regards,
