Don't ever hold overnight,always have your money working for you.I'm still stuck in one stock for over a month because I broke my rule of holding overnight. LOL
Just scalp pennies a day,it adds up.
If you can't afford to buy 10,000 shares ,just buy cheaper stocks or buy less shares.
Make it your goal to get $100 a day then $250 then $500 and so on.
Stock market is a suckers game,just scalp all day every day.
Best of luck to you.
