This video, part of a trading course, focuses on the practical application of marking up charts to identify trading opportunities. The speaker, Sci, explains their personal thought process and methodology for analyzing charts, primarily using the 1-hour and 4-hour timeframes, and then scaling down to 5-minute and 15-minute timeframes for entries. The core of the lesson is about understanding market structure, identifying higher highs and higher lows (uptrend) or lower highs and lower lows (downtrend), and how to spot and capitalize on momentum shifts, especially during the London trading session.
