NAS100 ORB Fusion is an automated trading robot (cBot) designed for the US100 (Nasdaq 100) market, combining two distinct opening range breakout (ORB) strategies into a single system. The first strategy, Base M5 ORB, defines the New York opening range from 09:30 to 10:00 and initiates long trades when a 5-minute candle closes above this range. The second, M15 Scalp ORB, operates on an internal 15-minute chart, executing both long and short scalp trades based on breakouts, with stop loss placed behind the signal candle and take profit set according to a configurable reward-to-risk ratio.

Both strategies function independently and can be enabled or disabled separately. Key features include percentage-based risk sizing, automatic stop loss and take profit management, maximum volume protection, one trade per strategy per New York trading day, automatic forced exit, holiday and early-close protection for the Base strategy, live retry for unsuccessful position closing, and automatic position closure before market session end.

The cBot attaches to an M5 US100 chart, internally loading M15 data for the scalp strategy. Backtesting from April 2025 to August 2026 showed a 73.58% total return, 80.8% win rate, 1.79 profit factor, and maximum drawdown of 4.52%. It is suitable for prop firms and requires a recommended starting balance of $10,000.
