When the buying outpaced selling from institutional investors, you will see the market act as major accumulation. When the selling exceeds buying, you will see the market act as major distribution. Notice that institutional investors act the opposite of the market price movement. One way to observe market action is watch market action in the morning and afternoon. Morning are for most small retail investors and traders and afternoon are mostly money managers and big institutional investors. That explained last 5-6 days market went up in the morning and down in the afternoon, because big boys allure small retail investors in and sell into the rally.
