I see you've completely missed my point. You are comparing a very high
level scripting language (Easylanguage) with a real programming language
(C#). Of course the real programming language will be faster. Why - far
fewer layers of abstraction. With the Easylanguage abstraction we gain high
level functionality (Buy, Sell, Plot ...), simplicity and easy of use. We
give up performance and flexibility.
My point is, if your going to start out clean with a new application, and
top performance is your goal (which may or may not be the goal here) then
there are faster alternatives to the Dot net framework languages (C#,
VB.net, C++.net).
Microsoft calls the code generated by these Dot net languages "Managed"
code. Managed meaning its managed by and compiles to the Dot net framework.
Non Dot net compiled languages (Object Pascal (win32 Delphi), C++, C, VB6
and PowerBasic (thanks Mike Symth)) generate code that compiles directly to
the win32, Microsoft now call this "Native" code.
Its a given, any lower level language than Easylanguage will be faster, I
just though I would point out to some folks who didn't realize it that C#
and the other Dot net languages will always be slower, because of the extra
abstraction layer of the Dot net framework, that languages that compile
directly to the win32.
I have Tradestation running an a workstation with a 19" LCD in portrait
mode. I wrote a little utility app in C# to run with tradestation on that
workstation and the screen refresh rate on that C# app was horrible. It
reminded me of a java application. I rewrote that application with Delphi
(win32 Object Pascal) and the screen updates now pop on the screen.

There is no need to cry about Pascal and Delhi and Super Pascal, Super
Dupper Basic or C++. Last time I checked you couldn't use them in
Powerful Power Editor anyways! Last I heard they were making a
section in London Pre Historic Museum to display these technological
monuments.
By the you guys, I am gonna ask ya all a very personal question, don't
answer if its too embarrassing, are still using windows 95? And hating
Microsoft?
We are talking about EL being faster than C#. We are talking about
which language will give you the greatest flexibility given the base
platform offers the same features and functionality.
Who care if C++ is faster or not, you cant code in C++ in Tradestation
anyways.
And for C#:
1. This is very flexible and very powerful language integrated with
your OS.
In C# you can implement layers for any application domain you want
and its easy to support and extend.
2. You can implement any data structures you want. The only
limitation is your imagination and creativity, and no longer you are
suffocated by limited capability of EL and you DON'T need to use
external DLLS to implement a simple tasks which Pascal or EL where
never designed to carryout.
3. If you want something new in EL, that's not supported by Omega
what will to do? In C# you can easily and quickly implement your
ideas or hire from a pool of millions of developers C# programmers
who can help you.
The average cost of C# programmer is about $35 per hours and lower if
you go offshore! Now compare that to the $175 per hour you have to
pay for the snoby EL programmers most of them are not qualified and
type with 2 fingers.
4. Speed? Speed of C# faster than EL. PERIOD. I have a conducted lot
of experiments in this area - and C# really faster on all stages of
processing of data. AS I said who care if C# is little slower than
c++, that's irrelevant here. An optimization run in c# takes about
1/5 of the time it takes EL! And no I am not using a genetic
optimizer addon of a addon to run along EL which is yet another
addon! Add all the addons together in Tradestation and you will know
what I mean!!
5. Also you have the entire Microsoft team working for you. As .Net
is just starting mature, it will get faster. As I said already .Net
2.0 is about 30% faster than currently implementation.
6. I am bored.
7. Regards,

Subject: Re: Advanced Trading Platform using C#.Net
I guess someone needs to come to the defense of Pascal and I guess
that someone will be me. Delphi uses Object Pascal which is a modern
object oriented language just as C++ is an object oriented version of
C.
Easylanguage is just a very high level scripting language.
FWIW, the problem with C# is that it sits on top of an additional
abstraction layer - the "Dot net framework". This is conceptually
similar to how java sits on top of an additional abstraction layer -
the "java virtual machine". When you run on the Windows platform,
both of these abstraction layers sit on top of the "win32". Object
Pascal, C++, C and VB6
sit directly on top of the win32.
Anytime you add an additional abstraction layer you get something and
you give-up something. With java you gain platform independence.
With the Dot net framework you gain language independence. When you
write to the Dot net
framework you can write in C# or VB.net or C++.net and the resulting
intermediate code is virtually identical.
What you always give-up with additional abstraction layers is
performance. Whether that performance hit is acceptable depends on
the application. For typical business applications it's probably
hardly noticeable. But you won't see serious first person shooter
games written in a dot net language any time soon.

ROFLMAO ...Jeez, I remember when Pascal was a modern language. I
must be older than the dirt under Fred's toenails :)
funny, but true. <g>
Ahhh.. but I think Easy Language is more of an obfuscated version of
Turbo Pascal (a legacy from System Writer Plus) - maybe invented by
the Jetsons ..I think George's boy Elroy wrote it. ;-)
