Yep still used (pre and post trade, processing millions of orders and billions of market data events per day). I'd like to grow it into a successor to kdb, though kdb is very entrenched in finance and the company is extremely litigious (they threatened to sue me). F# is great too, and all of the other ML variants. We'll get there eventually, it's inevitable, but there's a lot of institutional inertia.
