Welcome to Jane Street

“You can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future.

Virtu’s, Flow Trader’s Optionality? Not So Much…

"Research is what I'm doing when I don't know what I'm doing." - Wernher von Braun In the hierarchy of preferred trade types, the riskless trade sits at the top.
