Should the pattern in this chart trigger (break below 1530 on strong volume) a measured move to 1400 is in the cards with the potential to test the trend line from the 2009 bottom around 1350. Volume signature is a textbook example of what one looks for in a H&S top validation. Not sure what the catalyst will be that has the potential to instigate such a violent move. (I am short IWM via Puts) Not a recommendation, just an observation! Good luck out there!
