vs 13-week average
- The trend backdrop is inactive, so price action has not confirmed a constructive regime.
- Price is below the Trend Line, which keeps downside pressure in focus.
- Price is below Fair Value, so the market is still discounting the latest tape.
- Next-week expectancy is negative at 43.01% based on similar historical setup states.
- Trend Line remains the key weekly regime level.
- Activity pressure is the gauge to monitor for confirmation or fade.
- A volume ratio above 1.5x would show stronger participation in the next move.
