“Of the various HFT programs that are currently operating, one of the least effective is the so-called “Buy the New Low” program. When a stock reaches a new intraday low, many day traders will go short to ride the downside momentum. This program then begins to buy the shorts from those day traders to push the price higher. This causes day traders to panic and to cover their shorts. Because the organizations behind HFT programs have almost limitless buying power, the plan sounds flawless. The plan quickly breaks down, however, when another large institutional seller is behind the trade and decides to dump their large positions.”
