Market volatility looks likely when U.S. markets kick back into gear following the holiday break, so traders should keep a close eye on key price levels. Here's what's worth monitoring:

The yellow line marks the daily candle price box, which gives you the broader directional picture. The red line shows the 4-hour supply zone—where sellers have historically stepped in. This shorter timeframe can be crucial for catching near-term moves.

The critical thing right now? That 82.6K level absolutely needs to hold. Lose that support and you're looking at a potential breakdown. It's the line in the sand for bulls. Watch how price interacts with both the daily structure and the 4-hour supply pressure when markets reopen. If buyers can defend 82.6K while absorbing the supply zone, you might see continuation upside. Fail to hold it, and we're likely seeing a retest of lower levels.
