$US30 - Watching 52600 closely

Seeing $US30 push hard towards the 52600 area again today. It touched 52623 earlier, but the intraday high has been met with sellers each time it has probed above 52600. It's a clear resistance zone on the daily, and if we can't get a clean break and hold above it by end of day, I'm expecting a retest of 52300-52400. A strong close above 52650 would invalidate that short-term bias for me.
