I am very familiar with the site. It uses strictly candle stick patterns to decide. Just so you know it predicted that short on 6/5 and look what happened the next six trading days. It actually pulled the short and stated stay long. It changed back to short after down trend began. This site is not very technical and basically tracks trends. For example it will recommend a buy "after" a decent run-up already started. Not bad mouthing but this site is a trailing type indicator. Definitely not the end all to TA.
