I meant a genuine fraction. So you have arbitrary precision.
Yes, variable length fields are a bit annoying. But my argument is that the exchange itself doesn't need to be that fast. And the market makers just need to be faster than each other.
(For anyone else, exchanges just need to be fast enough.)
Yes, just using a 64 bit integers is probably the easiest here.
Floats would be worse than my suggestion to use variable length rational numbers, for exactly the reasons you know.
