Order block invalidation: when to delete the zone and move on

This is day 37 of the 100-Day Challenge, in the Liquidity & Smart Money phase. Liquidity pools, BOS and CHOCH, order blocks, fair value gaps and multi-timeframe analysis.

The lesson is built around a video we went and found from The Trading Geek, the clearest explanation of this topic that already exists, followed by an exercise you do on a real chart, which the AI then marks. 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.
