I will be including in the "A Great Day Trading " series a new written journal that records real-time strategy and trade location based on the structural aspects of Auction Market Theory. The link is A GREAT DAY TRADING. I have created a new spread sheet that allows you to track the volume for each 30 minute period during each day for comparative analysis of the NYSE Composite Volume. Don't forget to subtract the current figure from the previous figure to get the net amount of volume for the respective 30 minute period. The NYSE site will refresh every few seconds. I will be using this data correlation in my work and will be expounding on how I use it in my Day Trading Snippets work this year. Here is a snapshot of it.
