ORB_BRSTrading is an indicator implementing an Opening Range Breakout (ORB) trading strategy aimed at capturing momentum during the most volatile period of a trading session. It defines the opening range high and low based on user-specified time parameters and automatically calculates breakout levels. The indicator monitors price action for breakouts beyond this range and generates trade signals according to breakout direction, with optional filters such as volume or volatility. It provides visual alerts to confirm breakouts and supports multiple timeframes and instruments, making it suitable for intraday traders seeking high-probability setups. The strategy is applicable across various markets including Forex, stocks, indices, and symbols like BTCUSD, EURUSD, GBPUSD, XAUUSD, NAS100, and USDJPY.
