Hi, I am a net profitable trader and is getting better. What I do is very simple but it does take some serious thinking and observations. I am trying to learn many things now to improve on my performance. I am trying to pick up programming to code my system ( have not started yet ) and do away with the "discipline" problem that pops up every once in a while. I am going to learn more about options on top of what I already know. There are many more things I want to learn and so little time. BUT WITHOUT DOING ALL THIS, I am already profitable. So, I cannot understand why so many hedge funds or so called big boys find it so difficult to maintain a consistently profitable record. I know size do pose problems but even if you look at the smaller ones, they are not doing very well overall. With their financial muscle, they should be able to codify any profitable systems and thus have no "dsicipline" problems or employ the best discretionary traders, they should be able to work out all kinds of correlations or autocorrelations(whatever), intermarket relationships etc etc. They can employ the best brains in quants or programming and possibly the best traders. They should be doing a lot better than what we see. What is happening here? Am I missing something? In fact, I am perplexed to be able to extract money from the market given their advantage over me. Your opinions please.
