Answer
One at a time and in the order you asked: where can i view stock market data for free? yahoo finance where can i buy and sell stocks online cheap? different brokers offer different services for different prices. the least expensive i know of is tradestation.com or interactivebrokers.com do i pay tax on the profit? this is a q best answered by an accountant. how much would i need for my first investment? again, different brokers have different requirements for opening and trading in an account. i can tell you this: in order to day trade or be a scalper - buying and selling the same stock on the same day, the sec [securities and exchange commission] requires a minimum balance of $25,000 u.s. when you buy and sell shares through a bank, you may not need an on-line broker. but this is something you should ask about. can i buy and sell shares at the age of 16? you should also ask this q of the brokers or banks you contact. thank you for asking your question. i enjoyed taking the time to answer it. you did a great job - not only for your information, but for every other person interested in reading my answer. thanks to every one for reading my answer. vty, ron berue yes, that is my real last name
