Although the cheetah is the fastest animal in the world and can catch any animal on the plains, it will wait until it is absolutely sure it can catch its prey. It may hide in the bush for a week, waiting for just the right moment. It will wait for a baby antelope, and not just any baby antelope, but preferably one that is also so sick or lame. Only then, when there is no chance it can lose its prey, does it attack. That, to me, is the epitome of professional trading.
