Hello- I tried using the IB TWS to set up a combination order to buy a euro contract and sell a yen contract. I thought I did it right as the line looked okay on TWS. But when I transmitted the order I got: "ALL OPTIONS AND FUTURES IN THIS COMBO MUST HAVE THE SAME MULTIPLIER" The TWS "contract info-description": says: "Underlying: eur, jpy Security Type: Int Mkt Combo Contract: + (1) 6EU5 - (1)6ju5 Exchange: SMART Currency: USD Combo Multiplier 125,000 To sell 1 Int Mkt Combo means: 1: Sell 1 EUR FUT SEP05 (125000) GLOBEX 2: Buy 1 JPY FUT SEP05 (12500000)Globex" How do I set up an order to sell one eur and buy one JPY globex contract? [I never encountered "Exchange: Smart" perhaps that is the trouble?] Thank you.
