The most important thing is to have a good money management and follow it strictly. I was taking too huge risks before,and now I am following the system of 2%.This means that my SL should not be on a bigger distance of 2%. When I trade 1k account, I place a SL that will make me max 20 dollars loss. So this way I calculate the lots. And it is really logical, and since I started using it I have improved my results.
I learned that in the course Manual professional trading from EA Forex academy, it was 200EUR course, and this week I saw they have a sale so the course is just 10EUR, how ever I took few more...hope it helps
