Actually, correctly sized outraday traders have minimal drawdowns. That is the idea behind being correctly sized.
In fairness. a correctly sized daytrader also has minimal drawdowns per trade, but the extra activity results sometimes in long strings of whipsaws . In addition, a daytrader seldom gets the big homerun trade that extremely successful trading mandates.
Per contract is not an important consideration. Percentage of TLNW, however,is. Stop losses must be chart based. Once you define your stop out point, you can then figure how many contracts to trade. If it is less than 1 contract, then you do not take the trade or perhaps you could go to the cash index.
