I can leverage up about 4x when markets are open (only 2x overnight). I'd like to employ the capital that magically comes available every day--which means day-trading--but how is day trading anything but a gamble? With all the talk of resistance levels, moving averages, trendlines, etc., what stops a big player from dropping a massive trade and smashing your position? Perhaps in the ULL world where you're first to market on everything, I can see an advantage; or, if you work for Goldman and have every advantage at your fingertips; even better, a connected hedge fund with billionaires in their golf course foursome and a trading app... yes. But retail day-trading seems to sit in the "no-man's land" between the above and swing trading--a dead zone where no discernible advantage exists.
