Before I started trading two years ago, I can see that although there is no hard rule of how much I should I have in my account to start trading, many brokerages will require me to deposit a minimum of $1900 dollars. I believe that amount is good enough to wet my feet however I don't think it is enough for me to trade for a living and that is not my goal to trade with a small amount. Mathematically speaking I could see that smaller accounts lower odds of achieving positive results.
