Please close the dark pools. That and naked shorting are unfair to retail investors and the companies that are going out of business.

Entities which are found to be breaking the law need to be punished for doing so. Failing to respond to the actions of malicious actors leads to instability in the system, an imbalance of power when there should not be one, and a loss of trust in the viability of the system itself. The punishments must be sufficient to discourage future attempts and breaking the law. If breaking the law and paying a fine is more profitable and the only consequence for breaking the law is that fine, why would anyone pursuing profit not break the law?

Regarding TSO- It is irresponsible to allow trading over and above the TSO. This amounts to trading synthetic shares that do not exist and allows market makers to game the system. Not having accurate and timely TSO information and control in a market where brokers have the ability to perform thousands of trades per second is unacceptable and amounts to a failure in duty. On market makers who act as brokers and PFOF originators or in concert with; there has never been a more blatant conflict of interest than allowing a firm to act as market maker, broker, and hedge fund.

I would like to begin by thanking you for taking our comments. I have a few general comments before I attempt to address any of the points raised in your "Background and Discussion" and "Request for Comments" sections. To summarize my position: how is it possible that in an era of rapid trading in which computers execute thousands (or more) trades per second on any given security, that it is not possibly to simply and succinctly state the exact number of short positions taken against a given security (including synthetic shorts)?

1) make sure you receive correct data. 1a) if you don't, somehow make sure they do in penalties, that isn't pennies for short interest positions. Either make them relieve their position or ban them for trading for some time. 1b) don't let them self report giving them the option to lie. 2) ban dark pools. It does add liquidity, somehow. But at what cost? Especially with payment for order flow, these companies can front run any retail investors, without affecting market price, before the end of day. I want market transparency and fairness.

Hello and good morning/afternoon/evening. I'd like to start by thanking you for being open to comments from retail traders. I am not the most financially literate person in the room, as my experience investing has been limited to this year, but in that time I have made great strides in learning how our financial system functions. I parsed Regulatory Notice 21-19 myself so that I, as a young American and novice investor who looks forward to a lifetime of activity and learning in the free market, could provide my original thoughts. "A.

I'm a retail investor, of the style that invests my meager retirement in ETFs and other low-risk vehicles. I've recently become more interested in managing my own IRA and such, in part due to the fervor surrounding GME and other tremendously short sold stocks. This interest let me to reading extensively about short interest, reporting, FTDs, and the options techniques used to "hide" short positions from the lit market. At one point, during the January runup initally with GME, for a short while GME was >100% short.

FINRA 21-19 is a long overdue change. It is clear that the integrity of the United States market has been strained to the edge of disaster, in large part due to systemic risk developed under the regulatory authority of FINRA's outdated short interest reporting policy. While many of the policies mentioned in Regulatory Notice 21-19 address the general breadth of exploitable and ineffective reporting, they also leave significant specific gaps that could compromise the entirety of 21-19's purpose.

The time is now to fix this broken system. I am not leaving.

The confidence in the US market is waning and will collapse in time. For too long FINRA's out-dated short interest reporting policy has allowed malicious activities to continue with little to no oversight in the form of abusive and extraordinary over-leveraging of short positions. Many of the policies mentioned in Regulatory Notice 21-19 address the short interest ineffective reporting, yet, they also leave significant holes that compromise the entirety of 21-19's purpose, almost as if they were left this way.
