i am new to trading an have never traded before, and by watching the video lessons i don't learn anything. he doesn't explain where he buys his stocks and how he does it, he just shows when he bought the stock, how did you learn it ?

@mysuccess - My suggestion would be to get a tutorial from the broker you will use, That tutorial will show you how to place trades for either buying or selling stock on their software. Example: You would contact TD Ameritrade if you wanted to use their platform and they have tutorials on how to place the trades and what the different kind of orders you can put in to either buy or sell,.

They say i need to have 600$ before i begin. Does that mean they need 600$ from me to use or do i just need it to trade

You just need it to trade, They want a certain amount to open the account. Which broker are you looking at?
