After years of on/off intraday trading, I think I finally got the basic technique down. In other words, I now have an EDGE. The problem is, I always feel this tension before / during a trade is put on... now I have read all the Douglas / Steenbarger stuff (by the way, Steenbarger is way better than Douglas), and I fully understand it's all about tossing a weighted coin many many times. And the size I am trading really has no impact on my personal finance. But for some reason, I just can't feel relaxed thru a trading session. Even though the EDGE allows me to have a high win/loss rate, I usually feel exhausted after a trading session and aroused emotionally, so much so that the muscle tension lasts long after the trading hours are over. Maybe I am just too much an intense person, maybe I am too much a perfectionist. I am very competitive, and have a successful career besides trading... but this is frustrating the hell out of me.. If I don't solve this problem, I know I will never be able to have a lasting career in trading. At this point I don't know how to approach this problem. Help, anybody?
