Query: Excellent service and delivery and excellent book

Coming from a very technical trading background, I was shaken when the author explained how I make the market rather than the reverse. Now I understand the market and how it works and my trading has gone through the roof! I highly reccommend this book as a 'must read' before you 'go live' and put real money on the trading table.
