If anyone is interested in a real answer to the question read on. This is a thread about a legitamate question, not more PDT whining.
An effective way to trade correctly is to have a written plan. A real business plan will prevent you from overtrading, give you a sense of comfort when you need it, protect profits, keep you from making mistakes, and other benefits. Lets face it, many of us turn into complete idiots when we turn our computers on in the morning and start trading. Have a plan and you elimanate this. I'm not suggesting you change what works or to trade mechanically. Just get it in writing. The way to correct trading ills is to analyze everything you do. Your plan is the bench mark. Without the plan it is IMPOSSIBLE to analyze or be consistant. I'm sure there are a few traders that are inhuman automatons (not an insult, I wish I could trade that way) and the emotions of Spock. You few perhaps don't need a plan (but you could still do better with one). For the rest of us humans it can take a consistant loser and make you a winner, given some time.
