My after hours quotes says the bid size is 2 and the ask size is 1. Is that the quantity of shares being bid? If it is, then someone is walking the price up with one and two share quantities. I don't think that stick in the morning.
For Ameritrade one has inside size which is the number of bids at that number, and the sized which is the lot size. For Ameritrade accounts you multiple by 100 the size number. Currently I see 1 inside for both Ask and Bid with the Ask at 4 or 400 shares, and the Bid at 1 or 100 shares. The TIE Specialist has the stack locked down for the weekend. S/he is usually quick to the trigger on closing bell for locking the stack. Ameritrade does not provide any AH level II service, maybe other brokers do.
