Why EURUSD is GBPying

It’s quite late, like 19:00 GMT and should be quite calm yet the EUR/USD pair is thrown back and fourth movin 20-30 pips within seconds. It behaves like under an economic news release but the spread is normal and all.

The candlesticks looks almost like GBP sticks with shadows spreading around without any remote logic whatsoever.

Someone know what’s going on?
