That is off by a factor of ten. From the CME website: An order for any quantity may be accepted for E-mini outright futures. However, orders exceeding a specified number of contracts as indicated below must be entered on the CME Globex system as multiple entries, each of which must not exceed the specified number of contracts. E-mini S&P 500: 2,000 for outrights and 5,000 for calendar spreads. E-mini NASDAQ-100: 1,500 for outrights & 5,000 for calendar spreads. All other CME stock index futures â 500 for outrights & 5,000 for calendar spreads. An order for any quantity may be accepted for E-mini calendar spreads. However, calendar spread orders for E-minis exceeding 5,000 contracts per contract month must be entered on the CME Globex trading system as multiple entries each of which must not exceed 5,000 contracts
about 6 months ago maybe 8 there was a little peace on there stating that the position limits for ES were 20,000. I was on there last night looking for it, but I could not find it, maybe they changed it again down to 2k. Not enough IMO..
I apologize the title is MAX clip size.. Which has nothing to do with position limit.. But for what it is worth I found it.. 20k is total position limit. Which it looks like you can scale into with clips of 2k Example. http://i42.tinypic.com/zyfqds.jpg
