Here is an example of the what avoiding the process of open outcry price discovery can mean. The trade shown in alert Awas from approx. 12:22 p.m.c.s.t. today. The trade involved selling 10K of the Sep. 120 calls (middle dial) at a price of 1'02, most of the risk associated with being long these calls was offset in the Sep. futures (left dial) at a price of 11626. This resulted in a volatility reading of 10.11% (right dial).Around this time on what is referred to a block trade, 10K of the Sep. 119 calls traded at a price of 1'28, alert B and pit sources indicate that futures were around 11626 at the time this trade occurred. Note the volatility reading associated with the price of 1'28, again right dial in alert B. Pit sources indicate that a fairer price for the Sep. 120 calls would have been 1'24 (alert C). The buyer therefore spent as much as $625,000.00 more than he would have had the order been placed in the pit where volatility was obviously trading much lower.
