Rebound to the 67,000-68,000 range, consider scaling into short positions. The first target is below 66,000; if it breaks effectively, extend the target to 65,000. Strict risk management is required.

Rebound to the 2050-2100 range, consider scaling into short positions. The first target is around the 2000 mark; if it breaks below, look for support testing at 1950, with light position sizing.
