Working on a buying and selling desk is probably the closest an workplace job can get to a sport. Focus and reflexes matter. On the opposite aspect of each trill of the telephone or ding from a pc is a shopper who desires to commerce. If ignored, they’ll cling up and name a competitor. Everyone seems to be sweating, owing to the warmth wafting up from stacks of computer systems whirring at capability. On a busy day, it’s unimaginable to depart the desk—making the job a feat of endurance. Simply as sports activities groups use code to speak their techniques, so do merchants: “cable, a yard, mine, Geneva,” interprets to “Brevan Howard, a hedge fund, is shopping for £1bn and promoting {dollars}.” Errors trigger swearing, shouting and generally the smashing of kit.
