tomcat, how the hell do you buy and sell stocks before the market opens and after it closes??
My understanding of it was the following: the market opens at 9:30 AM and closes at 4:00 PM, every Monday through Friday (NYSE). IF you place orders before/after the market opens/closes, the order will only be executed once the market opens.
I thought the charts that indicate a price change or volume pre/post-market only measure the orders that will be placed at the open. Nothing is being traded until the market opens, so when the market does open with a large volume then there is a gap in the price.
Someone please explain
