Quote from vikana:
In addition to the discussions so far, I'd like to add what i consider one of the most important aspects of becoming and staying a consistently profitable trader:
It's a relentless pursuit of improvements. I constantly review all my trades, analyze the very good and very bad days in detail, check all my routing and commission costs and constantly adapt my systems to what I learn. I realize that this easily could be viewed as a silly "search for perfection", but I simply don't know any other way to stay on top of things. I'm not looking for perfection, as I'm pretty sure that doesn't exist. I'm looking for that extra little improvement that will give me an additional .1c per share, improve the overall statistics, etc. After all it's a game of large numbers, and even the smallest incremental improvement adds up over time.
