L1 Pairing FAQs
L1 pairing is the comparison by CTM of mandatory minimum set of critical data fields on two sides of a trade. All L1 components must pair before proceeding to L2 matching.
The below table lists the L1 pairing fields on blocks and allocations and whether these fields are mandatory or optional.
|Field Name||Mandatory/Optional?||Further Information|
|DealPrice||Optional||Available as an optional L1 pairing field. Otherwise CTM uses this field as a tie-breaker.|
|ExecutingBroker||Mandatory||CTM supports broker matching groups (BRMGs), a mechanism that automatically selects an executing broker from a preconfigured group.|
|SecurityCode||Mandatory||SecurityCode is a normalized value. CTM cross-references and pairs it with the preferred identifier of your counterparty. Even if the identifiers are different, CTM paris and matchies on values you and your counterparty supply.|
|TradeDateTime||Mandatory||CTM pairs on the date component of TradeDateTime only.|
|QuantityAllocated||CTM uses this field as a tie-breaker|
