I am new to this site and fairly new to daytrading. I have some questions about trading before the opening bell and at the start of the opening. I have read to stay away from the open for anywhere to a half hour to an hour to let the program sellers get out and let the stock patterns start to evolve. Is this true, and if it is, what is the correlation between before hours trading and the open? Is anyone that is willing to trade in before hours taking a risk that their stock will be slammed by the program sellers/buyers?
