(Anonymous trades, volume hidden, Level 2 very active with 5000 full lots per 10 seconds visible non-news.)

I'm rounding up programmers that are interested. We might be able to have some MT4 compatibility for source files but my initial testing will be working on a rewritten EA implementing the protocol library directly. The protocol library is written in C++, I'm thinking of Python for EA development with a .Net version implemented automatically through IronPython -> IL -> C#.

I'm asking now about FIX versions, MBT might use Fix 4.4 with proprietary extensions. FIX 4.2 seems the most common.

Minimum account size w/MBT: $400.
