I follow the 'buzz' - the tickers where everyone think it goes to the moon - look at the psychology of other players - the more they dream and have greed - the better - especially promos are great this way - not a good idea to play stuff where the competition is stiff - some big board stocks have good active traders.
FNMA - ACA$ - TSL$ - (some APS / VM promos) - recently I played.
I also scan sometimes, but mostly hard to find good plays that way. What parameters do you use ? I like a high beta value and lots of dollar volume
