you have already answered much of what i was asking and i appreciate this, i apologize if i do not understand this correctly, but this is how i interpret what you said. the minis are traded globex 24, very liquid. the big contracts are traded in the pit but can be executed electronically. so my question is, can rt handle the bigger contracts electronically, i understand they are done in the pit, but it sure beats using the phone, also, have u ever had problems with liquidity on the big contracts. do u trade other exchanges such as kbot, where the value line contract is traded can rt handle other excnanges? i know u said they are going to do cbot and i think that will be beneficial, i know many dtraders who are starting to trade the dow, i think tn can bring in a lot more clients with just this 1 move. besides the naz and spmini do u trade any other contracts on the cme such as sp midcap nikkei, through realtick. basically, does rt handle everything on the globex. reason why i ask, i have a model that shorts the big longs the mini kind of like a index arb using hte same index. and can u write options on fut through realtick, in case u get a limit move to get out or reduce exposure on a position, thanks for all your assisstance in this matter.
