#USHouseMarketStructureDraft marks a turning point for Wall Street. This proposal aims to modernize the operating rules of American financial markets by improving transparency, competition, and access for individual investors. Among the key measures: the limitation of payment for order flow (PFOF), equitable access to quotes, and better oversight of dark pools. If adopted, this reform could reduce costs for small investors while imposing more rigor on large high-frequency trading firms. A crucial debate is now opening in Congress, with significant stakes for the very structure of the market. It remains to be seen whether the lobbyists will allow this wave of reform to pass.
