Subject: File No. SR-CHX-2011-21

Proposed rule change is in fact in accordance with the spirit of the Securities Exchange Act.

If customers are not allowed to cancel the stock portion of a stock/option order, bogus prints will be left on the tape and it will mislead all market participants. Whenever two parties mutually agree to cancel a transaction, they should be allowed to. CHX current rule set is inadequate regarding this fact, and the proposed rule change is necessary to maintain investors confidence and faith in the market place.

I vote to allow the proposed change.
