Panther agreed on the 17.73 being Res. however it will be filling a gap at that point, so between momo without prior resistance in the gap and the PR it has been getting lately it may just blow through that. Plus gaps normally go fairly well in fill into candle bodies not just the wick areas.
I would say the more important resistance would be 18.23 area and if it gets through it or stalls for a while, if it gets through 19.21 it has pretty clear sailing.
I further think the short covering is going to help this one immensely
