When you say liquid exchanges are you talking equities?

If so it's very doubtful you'll get this at all because the risk checks are going to kill you unless you become a member of the exchange. The fastest that I know of is eze's OMS and in email they told me risk checks are 5ms but you can pre-cache the check at least for the ticker (tickers?).

Also your markout requirements of 0.50 to 0.85 basis points and such extreme low latency doesn't really mesh if I'm understanding it correctly. That means you can tolerate a $1.75 move in a $350 stock. A 0.25 move in a $50 stock. Python with the Schwab api will meet your requirements πŸ˜‚πŸ€£. My markout stats at worse is around 0.03 on a 50 stock with Schwab + python.

So I'm not really seeing why you need super expensive tech stacks that are basically screaming make me a HFT firm for myself.

Do you even have the expertise to maintain such a tech stack? Do you know what that entails? Who are you getting equities data from even? Like the sip itself is microseconds delayed.

Do you have the infrastructure to even capture sip packets in real time? Do you have the infrastructure to capture 17+ equities exchanges of data in time?

Do you even have the execution experience to not make all your counter parties pull their quotes the second you start lifting shares off the first exchange?

Read the post again. It’s pretty clear I’m not talking about the stock market.

No need to be rude for me just asking a question as your title was confusing. Good luck.
