I day traded for years back in the day, like so many I switched to swing and never looked back, even a lot of the top day traders of the 90's are now swing trading. The overnight moves contribute sharply to the profits even though some trades have overnight moves that cause loses. I pay a lot less in commissions and let time in the market do the heavy lifting for me, I get to sleep in many days - a lot less stress and much more profit, it is a sustainable way to trade. Some of my trading is on Forex, its a fine market for swing trading, never felt I was robed by the banks or broker.
