EURGBP watching 0.8530 for a break

Been watching $EURGBP all morning, and that 0.8530 level is holding up as pretty significant resistance. We've seen it test it a few times already, hitting 0.8531 today, but no sustained push above. My scenario is a break and hold above 0.8530 could signal a push towards 0.8550-0.8560. However, if it rejects again and we start seeing bids dry up below 0.8520, then the downside to 0.8500 seems more probable. That 0.8500 is a key psychological level, and a breach there would invalidate my bullish lean for now. It's really about sustained momentum on either side of that 0.8530 right now; anything less is just noise.
