Question about stocks on Etrade?

[Common Sense]

Why eTrade? What is about them that fits your trading requirements? How many books have you read so that you don't make typical costly mistakes in the Stock Market?

If you had purchased FB @ $48.... and sold @ $52 your net would be +$60.
($80 profit.... less $10 to buy the shares and $10 to sell the shares). If you had done this in one day, that's called day trading. If you had done that in 2 days that's called swing trading.

It can take, on average, 3-5 years to learn the skills to day or swing trade. 90%+ fail.
So..... if it looks so easy..... nothing in the stock market is easy.

To day or swing trade I'd suggest reading 6-12 books on the subject. Concentrate on the psychology of trading and risk management. Once you've created your own strategy find a platform that specializes for day and swing traders

Good luck.
