Optiver US

ry year of its existence. Growth and expansion have been robust, with new people and new market opportunities. Presence in the US, coupled with our other offices around the world, allows Optiver to trade in every major time zone in the world--24 hours a day, seven days a week. Optiver US is a participant and market-maker on major US derivatives exchanges covering stocks, futures and options. Our trading strategies are developed entirely in-house. Though our trading is primarily screen-based, we maintain links to traditional floors via brokers in the wholesale trading market. These trading activities would not be possible without a serious devotion of effort and resources to technology. At Optiver, we see the interrelation of IT and trading as vital to the success of our business. Optiver US LLC is a member of BOX, BATS, NASDAQ OMX, NASDAQ OMX BX, CFE, NYSE Arca and NYSE Liffe. We are member and market maker on NASDAQ OMX PHLX, NYSE Arca Options, NYSE Amex Options, ISE, CBOE, C2, BATS Options, NOM, NYMEX, CME, CBOT and ICE.
