I have been reviewing a course recently. One of the big things it stresses is to paper trade for an exceptional amount of time. It recommends at least 9 months, or however long it takes to develop your skills so you win at or near 80% of the time BEFORE risking real money.
In my experience, practice makes perfect. It takes a long time to get good at trading futures. This is not an easy skill to master, even if you have it layed out right in front of you. There are tons of timing, and psychological issues one needs to over come. You also need to find, or develop the right method for you.
For me, I do two types of trading. I day trade, and on occasion I swing trade as well. I have a lot of little wins, with occasional larger ones. When I do lose, especially losses that are a bit larger, it's almost allways because I deviated from the rules. This was especially so back when I didn't understand them completely.
There is a certain "video game" skill required to trade with the proper timing. You can be right about direction all the over the place, but if your timing is wrong, you will lose anyway.
Let me ask you this, what kinds of entry, and exit rules was this course teaching?
