In March, 2022, We The Investors launched our grassroots advocacy campaign and focused our first efforts on ending Payment For Order Flow (PFOF) and excessive off-exchange trading. One of the changes we pushed for was the end to one-size-fits-all tick sizes. On December 14, 2022 the SEC announced the most significant changes to US markets in 17 years, and proposed the first changes to tick sizes since the end of fractions and decimalization. We fully support the SEC's efforts, but we believe that the rule proposals can be improved. We are determined to ensure that individual investor interests are properly represented before the SEC and in the public debates and discussions.

Our third comment letter focuses on the proposed changes to Regulation NMS. We agree with the SEC's desire to both optimize tick sizes and harmonize these changes, to end the regulatory advantage that off-exchange wholesalers enjoy over regulated exchanges. However, we believe that the proposal needs to be improved, and have put forward our ideas for improvement.

If you agree with it, please join us in our mission to end excessive off-exchange trading and incentivize on-exchange trading by writing your own comment letter (feel free to take any parts of ours you want) or by simply signing your name and filing this letter. There is strength in numbers, and it's time to show the SEC that individual investors have the numbers.
