There is buying every day. As long as there is volume, then there are equal numbers of shares bought and sold. All trades are both buys and sells. The confusion comes when the trade volume is classified as "buy volume" or "sell volume", commonly referred to as "buys" and "sells". It's an unfortunate choice of terminology that leads some to mistakenly think that on a given day more shares can be bought than sold, or sold than bought. Only shares that are traded count as volume. And trading requires a buyer and a seller. The classification of "buys" or "sells" just refers to where the trade price was in relation to the bid price and the ask price at the time of the trade. It can be useful as an indicator, but it can also lead to confusion.
