The majority of my clients were/are yield curve traders who are looking to transition away from the curve trade or are searching for an additional revenue stream to augment their existing fixed income market trading. They are typically surprised and pleased with the multitude of electronic spread trading opportunities in the energy markets. Some of the more common possibilities are: Nymex Crude Oil Calendars and Butterflys Nymex Natural Gas Calendars and Butterflys Nymex Heating Oil Calendars and Butterflys Nymex RBOB Gasoline Calendars and Butterflys Nymex Heating Oil Crack Spreads Nymex RBOB Gasoline Crack Spreads ICE Brent Crude Calendars and Butterflys ICE Gas/Oil Calendars and Butterflys ICE Gas/Oil Crack Spreads Nymex WTI Crude vs. ICE Brent Crude Nymex Heating Oil vs. ICE Gas/Oil Chances are that your present charting, news, clearing and electronic execution infrastructure accomodates the ICE and Nymex exchanges. In my mind, energy is a real spreader's market. Fixed Income spread traders who can model markets these markets correctly can indeed make a rapid expansion into these markets. The ICE exchange and Nymex have alot of educational materials free to download on their websites. The Nymex Crack Spread .pdf is an excellent primer. I still trade the Treasury markets every day, but it's nice to have energy and equity spread trades there to cherry-pick as well.
