EUR/USD climbed up. Is it time to buy or to sell?

EUR/USD, 4-hour (H4) TF

Euro started rising despite not having any support from important news. Technically, the situation looks like the beginning of an upward wave; however, there seems to be no strong upside potential, especially since a new rate hike from the Fed is ahead. High gas, heating and electricity prices in the Euro area is also a problem.

With this situation, it is safer to sell gradually, that is, ramping up selling volumes about every 80 pips. That is likely to prompt a large correction, or at most a downward reversal.
