Options trading, not what it seems. On paper it looks like it works. What they don't tell you is that if your position goes into the red they will sell it auto. Then if it comes good again you are out. So when you see the story about how you make money whether market goes up or down, nah, that's not you. Also the leverage can be horrendous and if there is a big fall you won't get out at the top, you will be dumped out at the bottom. Of course, some people can make it work but you need to be pretty skilled.
