The break lower this month has formed a consolidating triangle pattern which the market is attempting to break out of overnight and faces resistance at the composite low volume area shown above.

The week has opened above last week's value area and is currently testing my initial resistance zone at 2143.50-45.00. If we see responsive selling there, overnight support is at 2138.00-39.50 followed by the 2131.00-34.25 zone, which could still see buyers take control.

Acceptance below 2131.00 would signal short term failure by longs and would expect shorts to target the zones below.

Acceptance above the initial resistance zone would signal a short covering rally and attempt to take out the 2156 swing high from last week. The RTH range gap from 8-9th Sept remains open between 2158.00-2169.25.
