This is in response to a couple of postings for EL text books, etc.
In the end, you want to learn EL to express your trading ideas. By the
time you keep stiff upper lip thru the learning, you will feel good
about being able to read others systems but disappointed by still being
incapable of writing your own systems. The difference between Knowing EL
and being able to write sophisticated systems is the difference between
being able to write in English and being able to write an article for a
local paper.
Most simplistic systems entry level EL coders write don't work well. In
my view, it really take some general computer programming skills to
become good at writing good trading systems - you almost have to
overshoot it. EL is almost the same as Pascal. If you are serious about
becoming skillful in writing sophisticated systems, register for a
Programming in Pascal at a community college or buy a Pascal textbook.
Practice basic programming skills. It's a seemingly long but actually
short route. After that, EL is a piece of cake.
EL is getting increasingly sophisticated and less easy. It is almost as
powerful as a general computer programming language. The 2000i version
introduces in the great feature of reference function parameter, which
is the same as Pascal's "var". This allows us to write fast functions
because it can calculate multiple things during one invocation and pass
all the results back to the caller. But the concept is difficult to
understand.
Hope this helps.
