what is the easiest way to close my TWLO combo x+3 112p x-6 110p x+1 120c x-2 125c? l tried to close this combo but could not transmit, getting window saying it is an invalid order. IB customer service said 'You are not able to override the "Invalid Combo" or "No Trading" message. It is by design. When you receive that message, you can consider changing the quantities of the legs you are trading or breaking up the order into multiple orders. Per exchange rules, they will only electronically book Option / Option combo's with a ratio of 3:1 or less, with max legs of 4: Leg Ratios 1:1 1:2 1:3 2:3 1:1:1 1:2:1 1:2:3 1:2:2 1:1:1:1 1:1:1:2 1:1:2:2 1:1:2:3 1:2:2:3 1:2:3:3 2:2:3:3 1:1:1:3 1:2:2:2 1:3:3:' l tried to break down that TWLO combo x+3 112p x-6 110p x+1 120c x-2 125c to a 2:4:1:2 but that was an invalid ratio too,( your broker can do? also got told 'max legs of 4' , but on 25 Feb, first trade, TWLO, I had enter the combo 6:3:3:6 so is max ratio 1:4?
Don't get hung up about taking it off all at once. Take it off as a series of verticals. You'll get better fills that way since the market for verticals is more liquid. Select the closing verticals based on how much they affect the overall delta of the position.
