14th, 15th and 16th - Magic days for VIX index S&P 500 VIX FUTURES (CONTINUOUS: CURRENT CONTRACT IN FRONT) CBOE_EOD:VX1! titusj I just noticed that when the VIX index is traded on the 14th day of the month, if you open a long position near the close value you are almost guaranteed a very nice risk-reward ratio with a minimum drawdown. When VIX is not traded on 14th, this can happen on the 15th or 16th.
