Let's suppose that C and C++ are a bit faster than C#, that's fair to say.  But in the case of a Forex application a good chunk of the time is spent sending data back and forth over the Internet -- which takes a long time.  Often many milliseconds or seconds.  So, overall, would it make a difference if an algorithm written in C takes 4.5 microseconds and one written in C# takes 7 microseconds?  Probably not.  On the other hand, a developer gets a lot for free from .NET when using C#.  That is, when using C# you can write a nice application in a couple of weeks.  Using C or C++ it would take a year.

If you were writing a program for the next space shuttle or missile defense system, then the rate-limiting section of code would be written in C or assembly because every microsecond counts.  But when other portions of the program have delays of milliseconds or seconds, then developers will choose a language that gets the job done more quickly and correctly.

By the way -- I'm not suggesting it took a couple of weeks to create FSB -- no way.  My point was the same application written in C or C++ would take 20x or more longer to develop than a similar one using C#.  If you are thinking of learning programming -- which I think is a great idea and no where near as difficult to learn as many people think -- then C# is definitely the way to go.

Does that make sense?

MetaTrader is written in C++ as well as many other windows programs. Theoretically C++ must be a little bit faster than C#, however the programs algorithm has more dominant role for the performance.

C and C++ are excellent and I used to write on them years ago. However from my point of view, C# is better as a general solution.

Recently Mozilla created new programming language "Rust" as a replacement of C++ and use it in the newest version of Firefox. Rust shows all signs to replace C++ for the user oriented software.

I have a general question , only for education.
I was wondering for educational purposes only, what if Forex Strategy Builder was coded in C++ or C ?
Wouldn’t be better, faster  and Smoother ?

And If yes , then why did you coded it in C# ? 

Thanks.
