Sounds like HFT? But then your competitors are probably using an FPGA to respond in 300 nanoseconds, so good luck with that 5 microseconds tick-to-trade.

Why do you think everything has to be either manually submitted order or HFT?

Sending a response within 5 microseconds of receiving a packet seemed like a very HFT thing to me.

I don't even know how you came to the conclusion that I think that "everything has to be either manually submitted order or HFT" but that's on you.

No, that could be a lot of things. SCADA is what came to my mind.
