How does BID SIZE and ASK SIZE affect Opening?

  1. Should I pay any attention to BID and ASK SIZE prior to market open to a particular stock?

    How do I interpret if one more than the other?

  2. Personally I do not but would like to hear opinions from other traders.

    The first 5-15minutes is always going to be wacky and volatile. There are a lot of built up market orders placed when the market is closed and before investors go to sleep. When the market opens these need to get filled. Bigger bid and ask sizes are not uncommon.

    I'm a big fan of waiting out the first 15 minutes of the market before trading.
