The MSX capability was added to the MetaStock formula language for just such
a purpose. The built-in formula language in MetaStock was designed to make
it easy for simple calculations to be quickly and easily coded. Because of
this, many complex calculations are extremely difficult or absolutely
impossible to code in the formula language.
Without the addition of MSX, it was virtually impossible for us to add the
capabilities to the formula language that were demanded by our power users,
while preserving the simplicity and ease of use for our less experienced
users. While some of our users have been asking for traditional programming
structures to be added to our formula language (loops, array indexing, etc)
most of our users have no concept of these programming techniques.
MSX adds the ability for users, who may have a programming background, to
write virtually any complex indicator calculation. When a user creates an
MSX DLL, it actually allows them to add new functions to the MetaStock
formula language itself. This means that once written, an MSX function can
be used in a custom indicator, system test, exploration or expert. These
new functions can also be easily shared with other users by simple transfer
of the MSX DLL. Once the DLL appears on the other users machine, the new
functions are automatically added to the formula language for that machine.
MSX indicators are also extremely fast to calculate.

Guy,
Why don't you get MSX, then you can make the add on your self.
I don't think it is too complicated if you know C or C++ Pascal , Power
Basic.
