755.54 is acting like a brick wall today. $SPY has tagged it 8 times, crossed through maybe a dozen, but only held above for ~25 minutes before noon. That's classic resistance — price keeps getting rejected. When a level gets tested this many times intraday without sticking, it either breaks clean or becomes the fade zone. Right now, sellers are defending it hard. Watch for either exhaustion on the next test or a flush if it can't reclaim.
