It executes a maximum of one trade per day, managing all aspects of trading automatically, including opportunity identification, position sizing, entry, protection, and exit.

Suitable for both beginners and experienced traders, it operates with minimal user involvement and supports CFD trading accounts, with potential compatibility for UK spread-betting accounts. Historical backtesting from 2014 to 2026 demonstrates significant compounded growth, such as turning £50,000 into £4.6 million and smaller tests showing rapid account growth. The strategy uses a breakout approach with low trade frequency and is designed to avoid overtrading and emotional decision-making. Key risk parameters include a recommended minimum balance of $1,000, 5% risk per trade, and maximum drawdowns of 14.16% overall and 8% daily. The bot trades using market orders on a 10-minute chart timeframe with fixed lot sizing and includes stop loss and take profit management. It is compatible with Pepperstone UK broker and has a profit factor of 5.68 and an ROI of 1172.52% in backtests.
