1. How do you display the combined greek values for your entire portfolio? In the portfolio window, I am only able to add a DELTA column, but not gamma/theta/vega columns. 2. How can you build a combo order with more than 4 legs? 3. How can you view the combined greek values for a position you've built, but don't want to transmit yet? 4. If you've built a position of limit orders and are now looking to transmit them, how do you update the limit price of each order to make sure it's at midpoint before you transmit it? I know using a calculator and entering it manually is one way, but you'd think IB has some function for this. 5. After you've transmitted the limit orders, the option price moves around but the limit order does not. How do you update the order to make sure it's always at midpoint? Also if it's possible, can you select what midpoint you want, for example skew it a little towards the bid-side to increase the odds of a fill?
