Hi guys, I have a question about what excatly does 'HIDDEN ORDER' in Interactive Brokers does. I normally buy 10 contracts but use 'ICE BERG'. I hid 9 contracts and show only 1 contract and I place a limit order and negotiate with them. *** Now I found out there is 'HIDDEN ORDER'. What does it do? I mean if I hid all 10 contracts, how will I ever get filled when there is no trace of my 10 contracts? Please enlighten me. Thanks.
