SOES Bandits A slang term for traders who make rapid buy and sell orders, using the SOES system, in order to make a profit from small price changes. Investopedia Says: Since the SOES executes orders of 1000 shares or less immediately, an SOES bandit has a greater chance of profiting since the bid-ask spread is tight and prices are extremely accurate.
