Previous day levels A Previous Day Level Indicator is a trading tool designed to highlight the key levels from the previous trading session, such as the high, low, and close prices. These levels act as significant support and resistance points, helping traders make informed decisions. By analyzing these levels, traders can anticipate potential price reversals, breakouts, or continuations in the current trading session. This indicator is particularly useful for day traders and scalpers aiming to align their strategies with market trends.
