ProRealtime: http://www.prorealtime.com/en/
It’s written in Java so it’s cross platform. For the class I’m teaching, I base a project on modeling & backtesting in prorealtime. They have a rudimentary gridsearch optimizer and a decently comprehensive equity database. They have their own programming language but a fluent programmer can pick it up in < 1 hour. However, you do get what you pay for and it’s only useful for testing a price based model, you won’t be able to incorporate any outside global variables or your external datastream.
