> I personally don't care that my trade happens in a second or a minute because I'm a long-term investor The difference between a second and a minute could cost even the small investor many $thousands in the long term. I prefer milliseconds. If you're a buyer at $30 and a second is allowed, you're likely paying $30.30 or more due to front-running. Immediately after you buy it will be $30 again, so you lost 1+% in the delay.
