Americans thru last 30 years have slipped into a microwave speed of world, go to a restraurant 2-6 times a week and almost all expect their food in fifteen minutes whereas in the 60's, going out to eat was a special occassion and there were courses and one would be there a couple of hours.
You can't expect to pickup a "Daytrading for Dummies" book Friday and compete on Monday, yes trading is competition, trying to get that one extra tic, one extra point. It is like one is going to go to a runner's track and compete against the world's best runners and you have never ran before and thirty pounds overweight. You want to bet where you will end up?
Going at it alone is so damn hard, I have done well in my three decades plus of trading and I have had help here and there, and countless people who taught and had no clue how the markets run. So not only is one stepping into arena of folks who will bite off snake's head, you can't trust 95% of the vendors, and books, videos are no different.
It takes years of constant study, backtesting, forward testing, takes thousands of hours of screen time. So most people are bored after a few hours of not showing millions, and those who be trying for years would give up their first born to pull out $100 a day. Unless you have a death wish, or enormous amount of passion for life in the challedge with money being a result of this passion, people fail.
Hell, people can't balance their checkbook, they expect to learn to day trade? I never recommend anyone to learn how to day trade, too long to learn and reward to risk too low, long term trading provides much higher reward to risk, learn to trade off weekly bars. When you add up all the RISK on each single trade one takes in a day of daytrading to the reward, it mind blowing amount. If you risk $100 per trade in ES on 10 trades that is $1,000, how much have you made on ave for that $1,000?
Just saying most people don't have the dedication to what it takes to run with the fastest.
