Quote from oldtime:
It is my contention that the number one reason for failure is undercapitalization
If you eliminate lack of discipline, fear, greed and all the other things they talk about on the psycho forum
that leaves you with the problem of capitalization
I believe the number one reason is lack of education and that is only achieved with years of study and trading. I have meet many in my time that started with millions and blew it all cause lack of study.
I believe in my heart if you have a well backtested method, start with 5k and day trade the ES, it should be way enough to start one's career in our field. And if you blew $1500, you should close down your account and do mutual funds. Most will think this is untrue, but if you can't control your account, save the years of unhappiness and do anything else, it is long process to become very good at this cause of the constant changes within one's emotions. You have to be smart enough to form outstanding rules and dumb enough to be able to follow them flawlessly. You have to trade as if you don't care about the money and just concentrate on not taking a losing trade, at least this is how I do it. I take many plus one tick trades and a few full target trades.
