Daytime screen volume on New York Mercantile Exchange (Nymex)'s Globex system, licensed from Chicago Mercantile Exchange, has doubled since the 12 June launch but still represented a small proportion of electronic energy trading.
Volume had risen to a high of 140,380 across all contracts on 20 July compared to the 62,695 traded on its first day. However, volume on Globex has failed to reach as much as 25% of the total electronic energy market across Nymex and rival Intercontinental Exchange (ICE)'s exchange traded futures arm, ICE Futures.
