I am trying out CTS T4 and while it has a very good variety of futures and options spreads, one thing I notice is that it does not have accurate margin displayed intra-day. Instead, for options positions they just use round numbers such as $10,000, $20,000, or $30,000 etc. for the futures options positions, presumably based on some rough rule of thumb. Interactive Brokers, on the other hand, does have up-to-the second margin display, and I am used to having it at IB, although I was looking for alternatives to IB that had more energy and other spreads etc. available. Do TT, Rithmic, or CQG have accurate real-time margin display?
