I just finished reading the 1st chapter of the Logical Trader, v interesting, but i have a lot of questions...will need to read the rest of the book. http://www.thelogicaltrader.net/chapter.pdf
The round number is providing its usual batch of sellers, and last week's VWAP is 87.90, which I failed to see earlier, but I would be surprised if that's enough to stop the train.
