OneChronos Commission Schedule

OneChronos uses TradeLiquidityIndicator (FIX tag 9730) values in trade execution report messages values to communicate fee codes to our subscribers. The TradeLiquiditiyIndicator values are derived from the intent of the original order and the execution result, and will be unique alphanumeric strings containing up to four characters that represent the type of the trade.

Indicator Codes

The TradeLiquidityIndicator value is created by combining all relevant Indicator Code values for a given execution (for example a TradeLiquidityIndicator of “FH” would indicate a firm hybrid order, while a value of “CH” would indicate a conditional firm up hybrid order) and then, when the execution does not follow our standard commission schedule (i.e. for Expressive Bidding, Conditionals, Nexus), adding a commission code to indicate the rate.

In all other cases, the execution will be charged according to our standard commission schedule, and receive a TradeLiquidityIndicator value of “F”, or “FH”. These executions will be charged a commission of $0.0010, unless a volume-based discount applies (in which case it could be charged at $0.0007 or $0.0005 per executed share (see below Discount Tiers Pricing Schedule))

The base commission of $0.0010 per executed share is the same for all Subscribers, with discounts available based on a Subscriber's total traded quantity. Subscribers can pay lower commissions for standard firm orders executed outside of Nexuses based on their total volume for a calendar month compared to OneChronos' total matched volume for that calendar month. Until October 31, 2025, any discount will continue to be calculated retroactively on all shares traded for that calendar month. As of November 1, 2025, each Subscriber's pricing tier for a given calendar month will be based on its activity from the immediately preceding calendar month, rather than be applied retroactively at the end of each calendar month. For example, your base rate and tier starting for calendar month November 2025 will be calculated based on your executed volume as a % of OneChronos Total Matched Volume in calendar month October 2025.
