this question may sound silly. more and more HFT hedge funds colocate their servers with the exchange or brokers. the question is, if the server is very profitable, say, tens of millions per year, how can the hedge fund be assured the strategies will not be stolen? the broker company may have no interests stealing it, but the IT person managing your server definitely would be interested which is much more than their salary, and then reverse engineering your code. Please share your thoughts.
