Is the premarket NYB prices a good indication of where the price may open? I'm short a stock (not on purpose, unfortunately) that had better than expected earnings last night and the NYB prices aren't really different from yesterday. I'm wondering if I should get out of my position now on the ECNs (even though its 2 points above the best offer in the NYB). Or should I just wait for the open? I'm worried it'll gap up higher.
