Hamish Raw has an MBA from Cass where he specialised in financial engineering, in particular, the pricing and risk management of conventional options. Following the MBA Raw went on to the floor of LIFFE where he traded as a ‘local’, an independent trader trading with their own money. Raw operated as a traded options market-maker in Gilts, US T-Bonds, Eurodollars and Short-Sterling. During this time he designed and wrote his original software in 1986 which had a ground-breaking innovation, the sliding skew. During the stock market crash of 1987 his risk management software enabled him to confidently take advantage of the confusion in the markets. Raw subsequently traded on the Sydney Futures Exchange as a ‘local’ operating primarily in Australian 10 year bonds futures and options, yet again as an options market-maker. On returning to London, Raw was in the Short-Sterling traded options pit during the upheavals of 1992 when Sterling was kicked out of the ERM, when yet again his long gamma portfolio structure stood him in good stead. During the latter 1990s Raw engaged professional software developers to code his software which culminated in his forming of FFastFill Plc, a software company that he floated on the London AIM market in November 2000 at a valuation of £54.5m. Subsequently he returned to trading in Chicago where he made options markets in the US 30 and 5 year bond futures. In the autumn of 2003 he returned to the UK to found The Gaming Bourse which was a betting exchange to specifically cater for fixed odds bets on the financial markets. The exchange launch date coincided with its IPO date but unfortunately due to the Madrid terrorist attacks the IPO was pulled. TGB was subsequently wound up as further funding in the prevailing market was not forthcoming. Nevertheless, in the short time the exchange operated it was successful with £150,000 of bets matched on one football match on the exchange’s opening day. Since then Raw has intermittently traded, has written the definitive book on binary options, and has operated as an international consultancy, specifically in derivatives risk management. He has written a sequel to ‘Binary Options: Fixed Odds Financial Bets’ which will be called ‘Exotic Binary Options’.
