So You Want To Be A Modern "Trader": Here Are The Requirements

> "R" is a piece of [] compared to other stat packages like SPSS and SAS

Do any name-brand quant shops use SPSS and SAS, in preference to R, Julia, Matlab, Mathematica?

Not that I'm aware of. I think that's what my girlfriend used in her "Stats for Psychology majors" class.

Exactly...for many reasons:
1) spoofers are going to jail soon. The exchanges are creating algos to detect pulled bids and offers.

2) no one codes in C++ any longer....the code becomes unmaintainable.
Heck, Tradestation almost went out of business because they had a million lines of c++
code with no comments and their programmers left them.

3) "R" is a piece of crap compared to other stat packages like SPSS and SAS.

4) All "machine learning" buys you is a system that is curve-fitted and won't remain profitable for more than a few months.

C/C++ are going to be alive for a long time in this industry. You need to interact directly with the kernel for drivers in C and you also need to write code that is deterministic for real-time trading applications, meaning you can't just have the GC decide to envoke itself in a way you didn't anticipate. There are ways to control/limit the GC's behavior, but it's still just not how it's done.

This applies only to high frequency trading where nanoseconds count.
For systems with average-time-in-trade of minutes or hours, there's no advantage to using C++.
C# and Java are more than sufficient IMHO.
