Can you buy and sell stocks instantly

[pode16]

Hi, I am a teenager trying to get into trading, I am looking for any kind and experienced day trader to help me. I have been wondering for a while now how fast can you enter and exit a trade. Also I would like to know is there some type of broker that lets you complete trades faster and what other things in the market such as trading volume etc. impact your buying and selling speed.

Getting in and out of a trade quickly is called scalping, some brokers ban that yet lots of them allow that. you need a good internet speed and a very low ping to your trading server to be able to scalp in a very short time frame.
