Please, god, do not start day trading. Warning, angry rant ahead.
Every book, seminar, guru, or whatever that says they have the secret are doing nothing but BSing you and preying on the public's misconceptions about how financial markets work and how financial assets are priced. After all, if they have the secret, why are they wasting time writing books/essays/seminar speeches instead of retiring on their mega yacht from all that alpha they are earning? The answer, obviously, is that it is much more profitable to tell people they can day trade and then try and sell them a book than it is to day trade yourself. Sure they may have made some money early on, but the smart ones realized they got lucky, and selling books to gullible and credulous people is way easier than panicking in front of a computer screen seven days a week.
People get suckered in because a "friend of a friend" made $100,000 in two weeks, what they don't hear about are the vast majority who don't make any money, or the others who lose everything. We as human beings are biased to take outlier events and assume they are the norm, especially if the reinforce what we already believe or want to believe.
Say what you want about business school (and there are plenty of bad things to say about it), one thing that any reputable finance program will teach you is not even to bother trying to "game the system". One of my financial theory professors said something like this, and it stayed with me:"There are thousands of people smarter than you, working harder than you, with more tools than you have, analyzing every bit of data on every stock in every market. You are not special. You do not know anything."
You know what is a quick way to get laughed at to your face? Tell someone in the industry you are day trading on technical analysis you do by yourself. Unless you are a math genius with a PhD from MIT, you will not be taken seriously, and even then you better have results. Algorithm-peddling grad students are a dime a dozen. Any information you "discover" is 100% guaranteed already to be priced into the stock/option/bond/commodity/WHATEVER. Don't even get me started on options "gurus". If you think you have found the perfect, alpha-creating option strategy, than I have a bridge to sell you.
There are no such things as trading strategies. There are just the lucky, who crow and brag about how easy it is and how they have a great strategy that is guaranteed to work, and there are the broke, who are the same people just over a longer time horizon.
It a crapshoot, pure and simple. The only difference is craps players actually understand the game they are playing.
Just start a painting business, like a few other people said.
