Query: A Valuable Book!

Just a note to thank you for your recommendation regarding "Tools and Tactics for the Master Day Trader". Of the 7 day trading books that I have read to date, it is by far the most valuable, and easy reading as well. I also purchased the Oliver Valez tape on swing trading which was valuable as well, although the charts etc. that were displayed were not readable. Even so, it was still excellent.
