Hi - is there a way in IB to set an order to sell when the price makes a, say, 100% gain from the entry price? I can see trailing stop sell but not this. Thanks
Use bracket orders for profit taking. You can attach either a profit or stop loss, or both exit orders to any order you place. If you already placed an initial entry order, right click on it and select “Attach -> Profit-taker -> Limit”. https://www.interactivebrokers.com/en/index.php?f=583
It is called a "limit sell" order (LMT SELL). If you bought for price x, you put in 2*x as limit price. Your position will be sold once the price exceeds 2*x.
