Check out 5 01 /2 pm on the EU and UChf mainly but also changes on EJ and GU

I would never trade off just one clue - but when you get multi clue's with Time / PA / candles /levels etc -then the scalps are on
The UChf was in fact the better scalp so far - up 16 pips in total so far - whereas the EU dropped 13 pips
Hour change TW's are normally stronger than the 30 min TW's - but not always - i have some 100 + pip moves start after 31 or 39 mins past the hour - so never assume to only check on hour TW
