Is it possible to send a market on opening order to IB TWS with a % stoporder attached to it. For example I send a MOO order to TWS to buy AAPL with a stoploss of 2%. When it gets executed at 210, my stop-order executes when it gets below 205.80; if however the opening is lower, say 208.10, my stop order would be at 203.94. If this is possible would anybody care to explain how ? Thanks.
