I'm a new trader with good programming skills. I did discretionary etf trading for a month, but got frustrated after a month of hovering around breakeven. I set up tradestation to enhance my research about 10 days ago and have quickly reached programming proficiency on this platform. Unfortunately though, I haven't found a strategy with good results yet working 15 hours a day since I got the software besides fading MA crossovers (which is pretty weak). I'm stumped. I started out optimizing the gammut of canned indicator crossovers and slopes. Predictably no good. Then I introduced stop loss, pullback and profit taking exits. Surprisingly, still no results. I see potential in a few good areas, namely adaptive MAs, fractal efficiency, double screen systems, NYSE $UVOL and $DVOL data, and SR levels... largely inspired by this board. Still, I am struggling to make these work and feel like I've tried everything. I would greatly appreciate direction from writers of successful mechanical systems who want to give back and help out a beginner. How do mechanical SR systems work? What works?
