when a nasdaq stock opens, the symbol-SUPERSOES bid/ask quote color changes in TWS from beige color (indicative) to regular color (green/orange). how can one capture this event via API? in general, how do people capture the opening price via IB's API? it seems for NYSE stocks, the pre-market bid/ask quote is blank until the open, but not for SUPERSOES. also, both for nyse and nasdaq stocks, even the primary exchange quote shows activity (last price/volume) during the pre-market, so one can't differentiate between ECN's prints and primary exchange prints. i have called IB and posted on their board, to no avail so far. i have emailed their API support, but my last email took two weeks to get a response (still, better late than never, of course). so i am hoping someone here may know the answer, thx in advance.
