How do you trade this in InteractiveBrokers TWS? ES Futures and Futures Options is all electronically traded, so is easy. These are pit traded, so how to find out the latest price and then do Order Entry. thanks
spx futures options are lame. you can't get the b/a so i estimate it by looking at es options and spx index options, then submit limit orders. it goes without saying that you should never submit a market order. this was back when i traded them; i don't trade them anymore. you could probably get a price by calling your broker and they'll call the floor to get a quote.
