I oppose this proposed rule change. The rule will allow one person to decide to temporarily shut down trades on open exchanges, while leaving dark pool activity open for business. Most retail investors do not have access to these hidden trading activities, and the priviliged few who do will be able to profit off of the imbalance in the market that shutting off trade activity on an exchange would cause.
I fail to see how this rule promotes a free and fair market and seems likely to erode confidence in the market.
