Some nice scalps upwards coming into play again for the EUR. Wait for confirmation of signals, of course - don't catch a falling knife and make a "bet" on the bottom before having some certainty. The overall market uncertainty and novelty of the news, fallout and long-term effects still - there will be some strong volatility going forwards.
I wouldn't place scalps short because of my conviction that the underlying strengths are there in favour of the EUR over the USD, and that JPY will suffer some intervention and signals from Japan.
Timing is everything for scalping in this volatile conditions, and if you miss the "wave" then you better abstain, because if not you will be whiplashed and stopped out. Medium term trades based on technicals seems very difficult in this erratic market - but then I'm not a technical trader.
Some tout the strengthening of USD and JPY as "flight to security", but then they are mislabelling technical effects of repatriation. Is repatriation a "flight to security" - well, maybe - but certainly not the belief that the currencies of USD or JPY are fundamentally any stronger - which is a gross misrepresentation. The JPY is certainly strong, but the balance of exporters and trade will weigh in.
