What is working

What could go wrong

  • Price is below Fair Value, so the market is still discounting the latest tape.
  • Activity pressure is negative, which weakens the current setup.
What to watch next
  • 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.
