    How many years are necessary to consider yourself a successful trader?

    Stock market is zero-sum game. For example, when the index goes from 20000 to 25000, every participant should gain roughly 20% in average during the time. However frequent traders usually pay lots of money to commission and tax. In my guess, most successful trader is NOT a frequent player.
