Say you have an account at a brokerage that doesn't have OCO (one cancels other) order functionality. You own 1000 shares of XYZ @ 10, and want to have a stop order @ 9 and limit order to sell @ 11 open concurrently. Brokerage won't let you tag the limit sell order as a long sale because the stop order is open. Is there any downside to entering the limit order to sell @ 11 as a short sale? Other question is when you unwind the long/short (after your short sale limit order gets executed) can it be done internally by the broker, or do you have to go back to the open market?
