This could be OK for a scalp from short term downtrend resistance:

Only thing is that it looks like it's had a wave 4 correction to around the 38% Fib so may be due to break out and form a new high before a more substantial retrace. Currently showing an RSI breakout which lends weight to that but the day's not done yet so that may retreat.
