Yes, your first statement is correct.
Per your second question, most external formulas (dlls) are
indicators, and therefore are applied without any knowledge or concern
for the indicator's name, they only care about the price data.
However, this price structure that is passed in contains lots of
information that can be accessed by the dll, including the price data,
the security name, the security symbol, the periodicity (tick, daily,
weekly, etc.), the start date/time, the end date/time, and a few others.
Information regarding this is available in the Metastock developers
kit, but beware it requires a pretty hefty knowledge of C++ (or
Delphi) and is generally pretty tough to work with. And Equis charges
for it.
I think that I may work on a util function where you can pass in a
name and get back a true or false. Would that be useful?
Has anyone else out there got an alternative to this? Maybe something
with MSFL? I will admit that I know more about the MDK than "tricks"
and "workarounds" in Metastock.
