it seems that a lot of people in my firm day trade by scalping. While there is nothing wrong with that but I see scalping as just an income when you add up the various overhead costs and commisions. It seems that to me it doesn't make sense to risk 5 cents to make usually 5 cents back (even that sometimes, is questionable), and the risk/reward ratio isn't as attractive. My question is, how do you millionaires make it? I have a friend who trades, and he said he made most of his money by pair trading.
