Cboe EDGX starts charging for its Clock Service

In Washington, Cboe EDGX Exchange has filed to charge for a new Clock Service, a timing product that lets subscribers synchronize their systems with the exchange’s own clock. The filing is immediately effective, so the fee change does not wait for a separate approval step.

For trading firms, that turns a niche utility into a recurring cost. The service is optional, but it is aimed at market participants that care about exact timestamps, system alignment and the kind of timing precision that can matter in fast electronic markets.

A bill for the clock

Cboe EDGX put the core service at $7,500 a month, with a 1 gigabit per second physical port used solely for the clock signal. The exchange also set a $2,500 monthly fee for a redundant connection and a $5,000 one-time High-Accuracy Timing IP Core setup fee for each physical connection that needs it.

The exchange says new users get a 30-day free trial, and the service is available to members and non-members alike. But for broker-dealers, market makers and other firms that build their business around speed and consistency, even a specialized clock can become part of the infrastructure budget instead of a background convenience.
