I just read the words that are in capital letters and I think its enough to know what is the main idea behind the OP's post.

I agree with you and I think many of us will agree because there are some traders including me who tried futures trading and failed. I still remember when I double my money in a short amount of time but I did it thru many trades (like swing trading but in the futures). All of the profits and the initial capital that I used in futures trading got wiped out in just a single trade. I did one single trade mistake and I lost all of my profits and my capital. After that I didn't do futures trading anymore. Futures isn't for everyone. Futures is for the expert people and those who are ready to lose their money if they made a single mistake.
