too funny
pick one stock and swing trade with 20k - sell losers quickly and ride winners carefully (not overnight). i don't need to make a living with this and i don't intend to keep losers for more than a $100 loss. i opened an account with interactivebrokers.com.
A if you are not trading overnight , you are prob not swing
trading
B if you are closing trades daily and have an under 25 K
account the PDT rules will only let you trade 3 times
every 5 days
C if you can trade and only lose $100 when you lose
you are a master trader ... not an inexperienced one as you
say in your post
a better approach for you is to use the IB commission
structure to your advantage based on account size and
experience ... pick a portfolio of stocks and swing trade them
maybe 5 - 10 stocks and do it in a way that limits any loss
to only 1 % of your portfolio
good luck
