The best broker for scalping?

Hi all,

What is the best broker for scalping?

here is the conditions I think it should be exist on that broker:

no any restriction on scalping, I means I can open a trade and close it in just few seconds and with any number of pips profit, even less than one pip.

it would better to be registered at NFA and other such organizations.

support electronic banks, and fast in deposit and withdraw.

got good reputation between traders.

low spread+commission.

high leverage.

Why seek NFA?
