Stock Trading and Other Things

What are some of the best day-trading strategies that were known to be successful?

What I want to know is that how many times does a good day trader trade stocks during one single day and how does he/she do it? Is it like just chasing the trends and listening to the news? or there are other stuff that can be useful too?
Any opinion would be appreciated :)

1. I don't know of one single day trader that is actually successful for any length of time. Although they can all shine you on pretty good.

The biggest rule is - don't hold anything overnight. Clear out your positions at the end of the day.

2. The best trading strategies are the ones people don't talk about :-)
