Do I have to go through a broker or is there a way I can do it myself?Must use broker. If I can manage my own stocks, how often can I buy and sell?As often as you wish and have funds to settle the trades with. Could I hypothetically buy and sell stocks all day, for pennies of profit?As much as you could hypothetically divine the lottery numbers from a dream you had.Buying and selling individual stocks has many risks and costs. One of the big ones for someone who wants to get into active day trading is the commission charges. These are charged when you buy and sell a stock. So if you do this often, these fees can eat everything you have. And I dont mean they can just eat away at your gains. I mean you can actually get down to a 0 balance if you do this. Is there a limit on amount of purchases and sales per time period?Only what is limited by your brokerage and their rules for the clearing and settling of trades and funds. Im under the impression its better to invest in high-risk stocks at my age - is this correct?Nope. It would be better for you to have a stock heavy asset allocation but this would best be done by buying an total stock market index fund. Is it a good idea to put all of my money into stocks or some sort of investment besides a savings account, or should I keep some of it in the bank?Before you do any investing, it would be best to have an emergency fund with 6 months worth of expenses. Since you declare that you have 0 of expenses than it would be best to figure out how much a car repair or a sudden airfare to visit a dying relative or such will cost and make sure you have more than enough to cover that. Then you can start investing. As long as you have earned income, then I would recommend you open a Roth IRA first, and contribute up to the 5,500 limit.Always remember, it is not about timing the market, but time in the market.
