You are long BHP.
Enable OCO orders in the page layout columns.
Then create a sell Limit order at your target for BHP and name it "BHP bracket" in the OCO column then,
a Stop Sell Market order and name it "BHP bracket" in the OCO column.
Hit transmit on both orders.
You now have your bracket orders a limit order with a linked stop. Just test it first. You know DYOR stuff.
TH - Thanks again, appreciate it. I will give them a try in my paper trading a/c.
I changed my order ticket view to comprehensive and it's all a bit different now. Lots to learn in TWS and I'm already starting to wonder if there is a front-end interface that's suitable for folks who trade multiple stocks.
