The key flow giving EURUSD support is a firmer EURJPY ahead of the BoJ decision early Tuesday.
If you want to sell JPY and not force the BoJ to intervene, one way is to follow the path of least resistance, which is on its crosses.
The chart shows 3 levels of resistance above the market and on the downside, needing to hold the 162.17 level to keep a bid.
As SF Monege pointed out. the prudent approach is to step back and let the dust settle on the BoJ decision as all that is certain is that there should be volatility following it.
