You are said idiot. Go to Ihub and click on trades. It tells the trades that happen at the bid, ask and somewhere in between. If it happens on the bid, people consider it a sale. If it happens at the ask, people consider it a a buy. IRL every trade has a buyer and a seller, but it is better for a stock to trade at the ask. Is this news to you? Stop responding to me if you can't figure that out.
