Quote from bigbob:
A veteran CME currency trader that I used to sit next to told me about this one. I know I don't have the numbers exactly right, but they were of this magnitude. At the CME, you should always put a size on your bid or offer. If you don't, another trader trader can pretty much stuff you with whatever size he wants. Anyhoo, back in the mid 90's in the Eurodollar futures spread area, A floor broker steps up and asks for a quote on a certain futures spread. Another broker steps up and yells "Half bid!!"
Floor broker 1: "What's your size?"
Floor broker 2: "I'm half bid!!"
Floor broker 1: "No, really, WHAT"S YOUR SIZE?"
Floor broker 2: "I'M HALF BID!!!!"
Floor broker 1: "Okay,...Sell you 27,850"
Floor broker 2: "make it 28,000"
Floor Broker 1: "done."
