Hi All, Wanted to check if anyone had this issue with IB/TWS. I was able to attach a profit taker with combo order but not able to do it anymore. Tried to get an answer from IB since Feb and not getting any good response. Here is the sequence: I create a pair with two diff instument --> open chart trading --> click BUY or Sell --> right click on Buy or Sell and attach Target Profit --? submit the order. Usually this will place both leg(buy and sell). But now I am getting the below error. It will only send the first leg(buy or sell). Any idea? "SELL 1 Combo @ xxxx for xxxxxxx" Child order can not be non-guaranteed combo I have also tried to submit from mosaic without chart and same result. Also, would like to find a broker who supports profit target with combo orders. IB has virtually no customer support. Thanks.
