A few years ago I wrote an article for SFO Magazine titled, "The 25 Point Mantra - Discipline for Day Trading" Rule #9: Earn the Right to Trade Bigger: "Too many traders think that because they have $25,000 equity in their trading account that they somehow have the right to trade five or ten e-Mini S&P contracts. This cannot be further from the truth. If you can't trade a one lot successfully, what makes you think that you have the right to trade a 10 lot?" "I demand that my students show me a trading profit over the course of ten consecutive trading days trading a one lot only. When they have achieved a profitable ten-day period, in my eyes, they have earned the right to trade a two lot for the next ten trading sessions." "Remember: if you are trading poorly with two lots you must lower your trade size down to a one lot." Question for everyone: What percentage of one lot only traders do you think are successful?
