10ms is way too long. Think about 3D graphics drawn at 60fps. That's 16ms you get for each frame. But 3D graphics calculates a LOT of stuff for your whole game in that time.

In trading you're not calculating nearly as much stuff.

In trading it's probably very sharp, the line between making and losing money. You want to be under 100us for sure. That's micros. Depends on what you're doing of course but 10ms is OOM to slow.
