Can anyone see Island hidden orders? I placed a hidden premarket limit buy order on Island using IB TWS. My order was not visible on the island order book. It was well below market price for the stock. There was a large visible order on Island which would take priority over mine at the same price level. I kept upping my limit price and the visible order seemed pegged to my limit price. During the opening cross, the other order captured the entire opening cross at an excellent price level. I was at the same level, but invisible and therefore at lower priority. Can some market participants see hidden orders on Island? Is there an order mechanism which can peg to hidden premarket orders?... or was this whole thing some sort of weird coincidence?
