Apologies if this has been covered but couldn't find the answer anywhere.
Is it possible to send MOO OPG orders via IB controller? As explained here:
I tried below with no luck:
orderID = ibc.PlaceOrder( symbol, "Sell", pos, "MKT", 0, 0, "OPG", True );
Basically, I want to get the opening print. With manual trading I always use OPG as time in force.
If not possible, maybe MKT or LMT is better, any advice?
