The Ukrainian issue will affect the EUR, but once EU makes a statement and gets a positive response from the public this will drive the EURUSD up. My technicals shows a BUY signal, I will stick to it and see how next week will unfold.
If you will play the EURUSD SHORT, you might want to wait till the strong bull candle last Friday gets cancelled. Price must break The demand region between 1.3720 to 1.3692 with a strong bear candle (check last Fridays 30m chart), then SELL the upward entrancement. This will reduce risk. This is my own view on the SHORT side, and not to be taken as a trade recommendation or advice.
