Like most traders, I started off with some basic strategies in demo, and lost money on all of them. Thinking that it was the strategies that were the problem, I hopped from trading plan to trading plan, trying to discover that magical combination of indicators that would make me money. I back-tested until I was sick of back-testing, and then back-tested some more. I came pretty close to burnout.
Mark Douglas and Dr Elder came to my rescue. They helped me to understand that I was the problem, so I went back to basics, trading with only a single indicator, and working on that strategy. My focus was on building a rule-set that managed me, and kept me out of my own way. I threw away most of the rules that people tell you are necessary for profitability (particular R:R ratios, don’t cap your upside, etc), and instead accepted that any profit would be an improvement.
After several months of profitable demo trading, I went live, and have been profitable in ever since. My profits have always been modest, but it is a foundation that I can build on. I still have a long way to go in my trading journey, and would never want to suggest otherwise.
