If it really WAS easy or free money, then realize that there are always more sophisticated and well capitalized entities in the market than you, and they would be mining out all of the value in that free or easy money, until that "free and easy" was priced into the market, and it would no longer be free or easy.
YUS!
I've implied this before, but if you're reading this post (or writing this post) you are a retail trading hack and a target for people way smarter than you, way better that the market than you, and with way more money than you (that they've taken from other retail hacks).
The goal is not to beat them, just to not be eaten by them and hopefully make a buck in the process. Your goal is to make sure your car is locked so the thief hopefully moves on to the net door handle down the street, so to speak. That's why IMHO some kind of price analysis is so important for ANY kind of position, whether you prefer technical or fundamental or some combination. That's why IMHO its worth understanding high probability market moves and how to position around them. Pro gap vs novice gap is a classic, for instance.
