Manual after-hours routing and open-outcry fill risk

Regular hours still meant the pit

While other futures markets were shifting to electronic matching, NYMEX flagship metal and energy futures still traded in open-outcry pits during regular hours. Open outcry is pit matching in which floor brokers handle paper flow during regular hours and can become overloaded when volume and volatility spike.

When those metal and energy pits were busy and moving quickly, floor brokers could be overloaded with paper, delaying fill confirmations so traders sometimes did not know promptly whether they were filled or at what price.

Members who earned their living on the NYMEX floor, and who effectively controlled the exchange, were not eager to replace open outcry with electronic matching. A new NYMEX open-outcry floor in London, intended to compete with an all-electronic rival, was described as unsuccessful from launch.

Overnight tickets still needed a clerk

NYMEX ACCESS was the after-hours platform for metals and energy, an electronic session used when the pit was closed. It offered no open interface for brokers to connect their systems and pass orders and fills automatically.

An open interface lets orders and fill confirmations move electronically with no manual rekeying or human search. Because that interface was missing, overnight metal and energy orders had to print at a brokerage desk and be keyed by clerks into ACCESS.

ACCESS neither reported executions nor alerted the broker when an overnight order filled, so staff had to search the system continuously and manually for completed orders. Fill confirmation is the post-trade signal that tells a trader whether an order executed and at what price; delayed or missing reports raise implementation cost.

Other venues already returned the fill

Other electronic venues, including CME Globex and the Chicago Board of Trade electronic platform, allowed brokers to route orders and receive fill confirmations electronically with no human intervention.

A possible open interface to ACCESS then under discussion was expected to cover energy futures but not metals. A newer ClearPort platform already used for e-miNY energy contracts was described in early reviews as far from perfect. Reported CME interest in a NYMEX stake raised the prospect that energy and metal futures might later trade on Globex.
