I am also a strong supporter of the rule because it would help to reduce the manipulation of share prices by market participants, by increasing transparency and by helping SEC identify and stop these practices.

I am deeply concerned about the continued lack of transparency in the markets and the lack of regulation in the dark pools. I believe that the SEC should require that all dark pool trading be reported in real time so that the public is aware of the trades taking place, and the SEC should require that all dark pool trading be reported to the public.

The SEC should also require that all dark pool trading be reported in real time to the exchanges so that the exchanges can monitor for manipulation and other abusive practices. The SEC should also require that all dark pool trading be reported in real time to the public so that the public can monitor for manipulation and other abusive practices.

The SEC should also require that dark pools disclose their trading algorithms and other information about their trading practices to the SEC and to the public. The SEC should also require that dark pools register as broker-dealers and be subject to the same regulations as other broker-dealers.

The current state of affairs, where dark pools are allowed to trade in the dark and to engage in manipulative and other abusive practices with impunity, is unacceptable. The SEC should put an end to this by requiring dark pools to be fully transparent and subject to the same regulations as other broker-dealers.

I strongly support the SEC's proposal to require transaction-by-transaction reporting of short sale orders. The current system of aggregated \"daily\" reporting is woefully inadequate, and results in a lack of transparency that harms investors and undermines confidence in the markets.

The current system also gives an unfair advantage to professional traders who have access to real-time information about short selling activity, while retail investors are left in the dark. Requiring transaction-by-transaction reporting of short sale orders would level the playing field and would allow all investors to make informed investment decisions.

The SEC should also require that short sellers be required to post collateral equal to the value of the securities sold short. This would help to prevent \"naked\" short selling, which can be used to manipulate stock prices.

The SEC should also consider prohibiting \"staggered\" short selling, which is a practice used by some traders to avoid triggering the \"circuit breaker\" rules that are designed to halt trading in a stock when the price moves sharply lower.

Thank you for considering my views on this important issue.
