These are our observed latencies for their risk checks after sending millions of orders per day for months at a time (which doesn't sound like much, and isn't much, but is the entire order rate that they gave us while we were doing 0.5% of the maker volume on their exchange).

So it’s not, as you previously stated, the time to compute a square root?

That seemed to be the most computationally demanding portion of their public documentation of the formulas involved

You’re stating confidently that python is orders of magnitude slower than it actually is because of some pseudo code, which you haven’t seen implemented, and you called into across a network link?

…do you see the problem?
