And here's my take on it --- this is only for TRADERS that are trying to game the system on a daily or hourly basis. They're trying to make PENNIES multiple times. I want to make DOLLARS for doing nothing - over a long period of time. I'll let them have their pennies.
I'm not trying to make it "nothing" but it's been going on for years. They're traders and that's how they try to make their living. I'm an investor... they're really really different strategies.
