Linux When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux. As late as 2007, Wall Street exchanges were still largely run on Unix . . . Over the past few years however, Linux has crept into this market, showing up first in ancillary systems and then running a few core exchanges.

Other reasons.

C++ for real time split second trading

The share's racket pays real good.

Several of the largest and fastest stock exchanges are written in Java. Make sure to never trigger the garbage collector, though.

Java excels on the back end and give extreme performance, if done right. C++ is not needed.

There was a study of algo trading apps, the Java version was fastest. Faster than C++.

JIT compilers can in theory be faster than C++. In the future we might see it.
