The daily low is the lowest price paid for an equity during a given trading day. On the surface it would appear that determining the daily low for a stock would be a simple matter. However, as stock trading evolves the precise determination of a stock's daily low is not as certain as it once was. The problem is not so much the definition of the term daily low as it is in defining a trading day. When the majority of equity markets were open from 9:30 am to 4 pm New York time, determining a stock's daily low posed no problem. Today, with pre and after-market trading, there can legitimately be some confusion as to what constitutes a stock's daily low. For traders who rely on a specific daily low for stock timing or other needs, it is important to determine what trading hours a data provider uses to determine a stock's daily low. |
