It even let traders know how useless stop loss can be.
What is you take on this? Do you have good trading psychology? Permit me to use good so that you can understand my question easily. If you are only scalping or day trading and using stop loss, I always think such people trading psychology is poor. A professional trader will scalp, day and be a swing trader when he sees the opportunity, but using low amount of money that fit each category.
I don't have issues with every other part of your post except where you make stop loss look really bad. Stop loss is used by professional traders because it helps you define your risk and takes you out of the market when you are too scared to close out on a losing trade. You can imagine trading a very big position and in draw down that's twice your normal risk simply because you failed to use a stop loss and accept you failure. Be it scalper, swing trader or whatever, using a stop loss is an ideal way to help keep not just your capital but your psychology. No one stops anyone from trading all three styles you method, but over time, I've come to notice that when you define what you want to see in the market and stick to it, you are better off on a long term instead of using different trading styles which distracts you.
