Primary Learning Objective
ORB is one of the more testable intraday strategies because its entry rules are relatively objective: the range is defined by the first period's high and low, and the trade triggers on a break of that range. The subjectivity lies in confirmation methods and context filters — and that's precisely where backtesting can clarify what actually adds value.
This article covers the data requirements for honest ORB backtesting (you need intraday data with correct session opens), how to log your results to reveal patterns across different session types, and the metrics that matter most for evaluating whether your ORB approach has genuine edge.

About Me
Krista Weber
After a career as a VP of UX and EdTech executive, I retired early—and quickly realized the traditional world of trading education is fundamentally broken.
As someone with a Master’s in HCI who specialized in the design of e-learning systems, I saw a massive gap: beginners aren't failing because trading is impossible; they’re failing due to massive cognitive overload and terrible instructional design.
This site bridges that gap. I’m applying the principles of learning science, systems thinking, and minimalist UX to strip away the market noise and teach trading the way it actually should be taught.
