Stock trading 24/7: eliminating the "dark zone", narrowing the space for manipulation

The US stock market currently operates within fixed hours (9:30 AM–4:00 PM). Outside of this range, liquidity drops significantly, and the depth of the order book is low — creating ideal conditions for manipulative behaviors such as spoofing (placing large orders and then canceling them before execution to lead price). The SEC and FINRA have repeatedly recorded these patterns in after-hours trading.

With the shift to a 24/7 model, the "liquidity gap" is almost eliminated. Cash flow is allocated continuously, allowing prices to reflect information in real time rather than being "shaped beforehand" in thin sessions. Retail investors are no longer passively waiting for the market to open but can react immediately to news — reducing the informational advantage of a small group.

This move is no longer a hypothesis. The NYSE has submitted a proposal to the SEC, Nasdaq has announced a similar plan, and CME Group is aiming to expand 24-hour crypto futures trading by 2026.

The foundation for this shift lies in blockchain and asset tokenization — enabling near-instant payments, reducing dependence on traditional clearing infrastructure, and eliminating time operating limits.

A cautious perspective: 24/7 does not completely "eliminate" manipulation, but merely changes its structure. As liquidity is spread out, manipulative strategies may shift from "quick trades during dead hours" to "navigating continuous cash flow". The core issue remains market oversight and liquidity quality, not just trading hours.
