How much capital, in percentage (on average), should one expect to lose in order to hang in there and improve their trading? I'm a newbie to this business and am currently down. I know that it is very easy to lose lots of money in the beginning, but its positive if you get a grip on how the markets work - and learn from those mistakes. So how much money and time should one devote (or expect to devote) in order to improve their trading profitability and winning consistency? Thanx for your input.
