I was monitoring the touch on 138.50 and wanted to get in at a double touch of that - even contemplated mid around .60 .. but I was a cheap bastard, but it's better to be safe than sorry. It's always good to secure some minimal profit as well - when it moves comfortably ahead of the entry - so that no matter what - you don't lose on a scalping trade.
It looks like it can do 141 - but it will need babysitting for getting in at a less optimum level above 139, as well as deciding on "fire & forget" - or - constant babysitting and trailing with a smart stop loss adjustment. I prefer babysitting really, but 141 might be well into the Asian session - which means late hours, therefore a sane small profit stop and 141 topside - or maybe even better - but it will probably be "two-timing touch and broken bones" (The Hives), so if it passes 141 it will trace back at some time too.
Right now - it needs to explode in a move through 139.50 to convince further. With only a few minutes to the US close, that seems unlikely right now - hence the need for a good entry to safe in profits and make a trade into "fire & forget".
