All I can tell you, is that I was using Market orders in far out contracts. I never used any limit orders. In some cases, such as the Jun 25 Crude contract, there was a crossed market, ie Ask lower than bid. Also, with the RJO platform, the Last price is used as a marker between bid or ask, sometimes that allowed me to create larger positions with more buying power. Whether or not this is commonplace I don't know, yes the figure illustrated in my example is very probably overhyped, but these are the results nonetheless.Well, genius, why don't you tell us how you made nearly 2 billion "units of currency" over several weeks time by trading forward futures contracts so far out in time that you would never get a fill at a desired limit?
