Do anybody use any other alternatives to PRT for automated systems? I have read about: ninja, metatrader, amibroker, python….  Any opinion about them?

Ninjatrader, my, amibroker Multicharts are trading platform but they are all allow automatic trading client side which means getting a VPS with Windows and keep trade with it.

Python is a general programming language that can be used to build algorithmic tradi platform as well as C or java but this is hard work to do.

Personally I would prefer a server side trading like the one proposed by prt, I will wait for IB integration.

And last thing is that using your own client side platform you will use API and not the FIX protocol that guarantee much better performance.
