Bearish on VIX, bullish on the market -- worst case loss, best case profit

I like the odds of  VIX staying below 26 for much of the next 16 days until the Nov VIX option expirations.  Did a bear vertical spread, selling 30 VIX Nov 26 calls and buying 30 Nov 27.5calls for a net credit of .45.  Tried .50 for a while without success.   The 0.45 order took about 5 minutes to execute.   The quoted net on this spread was 0.25.

The .05 difference between my initial and final offer was worth 30* .05 * 100 = $150, so it is worth a few minutes of effort to see if the market will bite.

The worst case loss on this position is 30*100* 1.5 (the spread between the 26 and 27.5 options) - 30*100*.45 (the net credit when opening the position) =  $4500- $1340 = $3150.  The best case profit is keeping the initial credit of $1350 -- if the November VIX options settle below 26 on the morning of the 19th.
