Stock market API for quotes?

(1) When you open an online individual brokerage account (such as with Ameritrade, Charles Schwabb, etc.), by depositing your money into it by check or money order for example, that brokerage account will have a window that shows you live streaming quotes. You can buy and sell stocks by selecting them from the streaming quotes window very rapidly. (2) Note that there was, and still may be, a requirement that you have a substantial amount of money in your brokerage account in order for you to be able to use it over and over throughout the day for day-trades.

Back in the 1990’s you were able to open an account with $1000 and use it for day-trading. Many people lost fortunes however in day-trading. Consequently a new SEC regulation made it mandatory in the early 2000’s to have $25,000 in your account in order to use your money over and over in the same day for day-trading.

I don’t know if this regulation has changed in 2015. (3) In respect to high frequency "machine trading" mentioned by jmm2112 it is true that they have an advantage over you. You can still make money as a day-trader; I do.

But you can easily lose money as well. You’ll figure it out.

I hope you realize that individual "traders" can never compete with high frequency "machine trading" practiced by large institutions.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
