Hello, 


I fully support the NMS: Minimum Pricing Increments, Access Fees, and Transparency of Better Priced Orders (No. S7-30-22) rule. 



The harmonization of tick sizes across all exchanges will be a big step in making markets fair to everyone. Too many exchanges get special treatment and are able to leverage that special treatment to build monopolies in some areas of the market. All exchanges should have to quote AND trade in the same increments. Some exchanges shouldn’t be granted an unfair advantage over others. It leads to monopolistic control of parts of the market that counteract and eventually kill the positive benefits of competition. The markets must be fair. 



I also support any structure that is clear and does not rely on vague language. For example, some funds and firms might request language like "has a reasonable amount of liquidity at the NBBO", and too often a favorable-to-wall street judge is who determines what a "reasonable amount" is. Loose language makes enforcement difficult or impossible, and wastes taxpayer dollars on needless litigation time. Clear language and a clear and unambiguous tick size rule structure are strongly preferred. Please do not include vague language in the application of your rules. 



Thank you.
