I guess tops and bottoms catching may not be a bad thing. Like if there is a nice resistance or support (I would go for horizontal lines - more reliable) and if you can put a tiny stop. The idea would be to cover from one nice trade for lots of bad ones (likely to be more losers than winners when going against trend)
Cable looks as if it's hit the top, but trend is up. I wouldn't go for it, but if I tried I would go for a short with a stop at 493 and if wanted to keep risk to the minimum (less than 10 pips) - I would need entry at higher price than 485
Also it's not my favourite to trade after 17:00
