Backtesting EUR/USD: building a statistically meaningful sample

This is day 61 of the 100-Day Challenge, in the Build Your Edge phase. Backtest, measure your edge and write rules you can follow.

This day is a hands-on exercise rather than a video: you do the work on a real chart or in your journal, and the AI reviews what you produced. One lesson opens each day, in order, so it becomes a habit instead of a binge. If you already know the basics, a placement check inside the course lets you start at Smart Money or Order Flow instead of Day 1.
