Sterling sits on top of the key level identified in the original post (currently at 1.4640). If it is going to move higher, it must do so now or the count above is negated.
EUR/USD is sitting on some minor support as well.
However, real time speculative sentiment index is a head wind. Sentiment is growing towards more longs (GBP/USD at +2.9 & EUR/USD at +1.1) so we have an elliott wave count conflicting with sentiment. Not a lot of conviction on this long, but might be worth a tight stop.
