Volatile markets generally are signs of tops. Swinging 3 to 4% a day is difficult to catch, and can lead to a lot of whipsawing ans second guessing. If you are day trading the S&P or Dow, you must lower your bet size and raise your stops. The S&P has support at 1918 and the Dow has support at 15,582. Buy it against those pivots, but be ready run fast if it rolls over. As for the Grains: I’d be a seller of rallies in front of the USDA tomorrow at 11.00. Some week one options are the cheapest way to play the market either to the upside or the downside. 5%= 16451 10%=15,551 S&P-1913 is 5% S&P- 1812 is 10%. Just in case you are looking for those key percentage drops as market entry or exit points. CER
