The "50 percent" indicator automatically detects the previous trading session’s high and low prices and calculates the midpoint between them. It plots these three levels—high, low, and midpoint—directly on the trading chart. This functionality helps traders identify key support and resistance zones as well as market equilibrium points, which are commonly used in reversal and breakout trading strategies. The indicator is designed to assist in technical analysis by visually marking these critical price levels for better decision-making.
