Been in this game for over 25years and yes we made money day trading back in the 90's but that was as a floor trader seeing real life bid offer in the pits . We scalped and won because we could see the big orders coming through from the brokers on the phone.
In todays world Day traders might have a lucky year and show a net positive result in a year but year on year they will lose. Fact is no day trader can sustain profits year on year. I have seen traders who have a had a few year lucky streaks only to lose everything they had amassed over the year and some more in a year.
Unless you are a bot you are NOT going to beat the market day trading.
If you are a day trader stop the gambling today and either go long term or if you still fill like gambling then go to Vegas where you will have more success.
