NAS100 Dual ORB is an automated trading bot designed for the US100 (Nasdaq 100) index, combining two opening range breakout strategies into one cBot. The Base strategy operates on a 5-minute chart using the New York opening range from 09:30 to 10:00, initiating long positions when a candle closes above the range with a stop loss set below it. The Scalp strategy uses internal 15-minute data to trade faster breakouts in both long and short directions, with stop loss based on the signal candle and take profit determined by an adjustable reward-to-risk ratio.

Both strategies function independently, allowing users to enable or disable either one. Key features include percentage-based risk sizing, automatic stop loss and take profit management, adjustable maximum volume, and a limit of one trade per strategy per New York trading day. The bot also includes automatic position closing before market session end, holiday and early-close protection for the Base strategy, and repeated close attempts during live trading.

Backtested from April 2025 to August 2026 with a starting balance of 10,000, the bot achieved a total return of 73.58%, an 80.8% win rate, and a profit factor of 1.79, with a maximum equity drawdown of 4.52%. It is compatible with prop firm accounts and designed for day trading on the US100 M5 chart. Risk management features include fixed risk percentage per trade and integrated stop loss and take profit controls.
