What is it that you trade?
As long as I know, trading is almost as fast as you can clic. The delta t being at the the speed of light.
Using limits, markets? give some details.

cmon, get real.
assuming you know the stock and the order, all you have to do is set it up in advance. then its a single click or hotkey.
If you trade using a market order or dont have to fiddle with limit prices, you can do a buy AND sell in under 1 second manually
