I agree you should watch different time frames. For example if there is a strong resistance on 4H chart then probability is high that we have at least a small correction on 5 min and 15 min charts.
It also depends on your trading style of course
Last month their EUR reserves declined so at least for now I think they will keep 1.20 level intact. This week they also opened office in Singapore to do more diversification and keep an eye on CHF.
