Longer market hours. More questions for your algorithm.

The conversation is moving beyond access

As of 13 September 2026, the SEC has scheduled a roundtable on preparations for 24-hour U.S. equity trading for 17 September. Its agenda includes broker and exchange readiness, overnight surveillance, market operations and investor protection. The event is upcoming at publication; its discussions or conclusions should not be treated as settled policy. See the SEC’s event page and agenda.

For people evaluating trading software, the useful question is broader than whether an app has an overnight button. What happens to the strategy, account controls and operational responsibilities when activity can take place across more of the day?

Additional market access may create possibilities. It also gives customers more reasons to understand the specific process they are enabling. A software subscription does not, by itself, establish that every product can or should trade in every available session.

An open market does not mean the same market

FINRA’s extended-hours risk disclosure describes possible lower liquidity, higher volatility, wider spreads and differences between trading venues. Orders can receive different prices or fail to fill. Those considerations remain relevant when evaluating a strategy intended for activity outside the regular session. Read FINRA Rule 2265.

A model designed around a particular closing price, opening auction or decision window depends on those definitions. Extending the available session does not automatically make its original assumptions valid at other times. Changing the operating window is a research and implementation question, not just a user-interface choice.

Consider a hypothetical strategy tested at a regular-session reference price. If you move its order to a less liquid period, you have changed an execution assumption. Whether that improves or worsens the result needs evidence. The fact that the broker now accepts an order is not that evidence.

There are at least three clocks

The first clock belongs to the strategy: when it evaluates inputs and changes targets. The second belongs to the broker and market: when the selected instruments and order types are accepted and executable. The third belongs to the operation: when data is refreshed, sessions are maintained and support is available.

Those clocks need to be understood together. A current target can exist when the intended execution window is closed. A running server can have an expired broker session. A risk condition can be detected when immediate liquidation is unavailable. Each requires a different response.

Before enabling a product, ask which window the current version is designed to use and what happens outside it. The answer should include rejected or deferred activity and what the customer needs to check, rather than treating every quiet interval as an error.

What persistent software does-and does not-provide

SquaredQ’s dedicated cloud environment runs the Reader independently of whether your personal laptop is open. That is useful for a configured automated workflow. It does not make every underlying service continuously available or every connected account eligible for every session.

Broker authentication, data access, instrument permissions and order rules still apply. The selected strategy retains its own decision and execution logic. A cloud instance therefore supports the process you have configured; it is not a guarantee of uninterrupted execution or around-the-clock human monitoring.

When evaluating SquaredQ, use the broker-specific guides and current product documents together. An integration being listed means there is a documented connection path. It does not establish universal 24-hour support for all securities, accounts or jurisdictions.

Know the risk action during an unavailable window

A risk setting should be read as an instruction to the software, with a defined response and known execution limits. If the selected action is to disconnect, existing positions remain. If it is to disconnect and close all account positions, the software attempts liquidation through the broker.

An attempt can be delayed or fail because of market or broker conditions. A threshold cannot guarantee a final maximum loss. Longer trading availability may change some opportunities to execute, but it does not remove halts, unavailable liquidity or account restrictions.

This is why the MyAlgo guide explains account-level scope and the separate activation boundary. Before relying on a control outside the usual session, understand the current instrument and broker rules and how you would verify the outcome.

How SquaredQ fits the next phase

SquaredQ’s relevant contribution is a documented connection between a strategy’s rules, customer-selected allocation and risk settings, and broker-specific execution. The product gives you a way to study those parts together instead of treating automation as an abstract promise.

This article does not announce a new 24-hour SquaredQ feature or claim that the upcoming SEC event approves the platform. It identifies the questions a changing market makes more pressing. Start with the strategy’s current construction and execution documents, then check that your intended account supports the actual workflow before activating.
