You just don't get it... That screen image is an exact replica of the Etrade L2. The red indicates a trade that is lower (or equal to) the previous trade. It is NOT an indication of whether the trade was a buy or a sell. Some quote services show colors differently. But even then we really don't know whether a trade is a buy or a sell. I have bought shares at the bid and sold shares at the ask. Your inexperience is betraying you. Goodbye and good luck.
