Having bought two April 130 calls the other day for 1.34, we can offer two April 135 calls short risklessly. Let’s try to sell them for 1.14, day order. If successful it will extend the range over which our existing position would be profitable while reducing its cost.  The rest of the position is as follows:  long the July 115-April 115 calendar spread twice for 6.00 (currently trading for around 10.50); short an extra April 115 call for 1.40; and, long two July 120-April 120 call spreads for 9.80 (currently trading for around 10.40). Time decay is working so strongly in our favor now that the stock could probably move $10 in either direction today — or not move at all — and our theoretical profit would only increase.
