I don't expect German ZEW to move the market. What can possibly happen here is that this data would trigger a bigger move [but obviously no price action will be caused by data, it's rather traders waiting for data to do whatever they wanted to anyway]. Additionally I do believe that big move can happen only in trend direction, so worse than expected data will keep me away from market. If data was better than expected I will wait for some small retracement on 1M chart [even if initial move will be down].

If EU price break below current 30M range low 1.4950 I would cancel all actions planed.
