Anybody hear of this guy? Looks like he's looking to make a few pennies via a newsletter service after trading for JP Morgan's STIR desk for seven years. I have no idea what it costs - looks like he's marketing his service to prop firms. I have ZERO affiliation with him or his company. Just curious. From the website (curveadvisor.com) The Curve Advisor was founded in 2011 by Joseph Choi. Mr. Choi was a senior proprietary trader in J.P. Morgan’s Global Currencies and Commodities Group. He was consistently profitable in trading Eurodollar butterflies over his seven year trading career. He was one of the largest discretionary users of Eurodollar futures and options, trading well over 10 million contracts a year. Mr. Choi started the Curve Advisor newsletter to discuss trade-specific market views on the Eurodollar curve and to help clients explore opportunities in curvature trading.
