Does any one have any experience trading SSF for QQQQ? 1. What is the ticker for the SSF for QQQQ? 2. Any volume? I know I can trade QQQQ directly. But that is not what I want. The reason I ask this question is that in some cases, I only want to trade futures (so no QQQQ), but do not have enough the remaining money to trade whole/one NQ contract, so I am looking to trade SSF for QQQQ for the remaining cash. I do not expect to trade SSF/QQQQ often so volume is not that big issue as long as there is some volume. Thanks for helps.
