One of the best jobs to get but one of the hardest is a clerk for a trader at the Merc. Most clerks send hand signals over to the desks or other pits but there is a job that I have only seen at the Merc (there are a few in bonds over at the CBOT) . The job is bodyguard. Some of the pits are so crowded and agressive that a big trader who has cash will hire clerks to surround him and give him plenty of space. That is their job, to check trades and make sure Mr. Trader has all the space and information he needs. The jobs pay pretty well and can pay $30,000 plus if you can get them. You also get the feels for the pits , get to meet other traders, and eventually could get backed and start trading.
