Spot trading drives FXSpotStream’s September record as Cboe’s firm liquidity share rises

FXSpotStream’s September average daily volume reached $179.12 billion, its highest monthly figure in the published 2026 series. Spot contributed $129.51 billion and other products $49.60 billion. The company reports the activity on a single-counted basis.[1]

Cboe’s 15 October review adds a different signal: firm liquidity reached a record 56.5% of its spot electronic communication network, or ECN. Firm ECN average daily volume was $25.7 billion, up 45.0% from a year earlier. Its overall spot figure was $61.6 billion.[2]

For a broker buying liquidity, the two releases raise related but distinct questions. Rising activity can make a connection more commercially relevant. The mix of trading protocols determines what the broker can expect after sending an order. Neither release, by itself, establishes the execution quality available to a particular client.

Spot accounted for approximately 87.9% of the increase in FXSpotStream’s daily total, calculated from the rounded figures. Total average daily volume rose 43.0% from September 2025. These comparisons use daily averages rather than confusing September’s extra trading day with underlying activity.[1]

Firm liquidity changes the execution decision

Cboe’s operating procedures distinguish quotes executable immediately against an incoming order from non-firm quotes that a market maker must accept or decline. Users can request firm-only, non-firm-only or mixed liquidity. With non-firm liquidity, the procedures also address what happens when an order is rejected or the review period expires.[4]

That distinction affects the meaning of an attractive displayed price. The initial quote is only part of an execution outcome if the order may subsequently be declined. A broker comparing connections needs to consider the eventual fill and the cost of finding another price when the first attempt fails.

The 56.5% figure must retain its stated denominator: Cboe’s spot ECN. It is not the percentage of all $61.6 billion of Cboe spot activity, and it is not a share of the global FX market. Cboe’s release also applies different counting treatment to some SEF transactions, making casual addition across product categories misleading.[2]

A larger firm share can justify a closer look at how a broker configures its liquidity access. It does not prove that every customer would obtain a tighter spread by selecting the same protocol. The appropriate comparison uses the customer’s currencies, trade sizes, timing and completed orders.

Access economics depend on the relationship

FXSpotStream describes a bilateral model in which customers trade with liquidity providers using existing dealing relationships. It says price takers pay no commissions, market-data, access or hosting charges to FXSpotStream, and that it does not add a spread or trade for its own account.[3]

Those statements describe the platform’s charging and dealing model. They do not make the customer’s all-in execution cost zero. The counterparty’s quote, credit arrangements and the price achieved when completing the trade still matter. A broker can therefore see a lower explicit platform bill while retaining a substantial reason to examine execution outcomes.

Cboe’s procedures likewise tie available liquidity to configuration factors including counterparty preferences, strategy, access method, spreads and historical acceptance rates. A platform-wide volume total consequently need not describe the exact pool a particular participant sees.[4]

September’s figures point to greater use of these venues and a larger role for firm ECN execution at Cboe. The commercial question is whether a broker can turn that activity into reliable fills at a competitive total cost. That requires its own transaction evidence alongside the providers’ volume statistics.
