Alongside with you I'm waiting patiently for ECB decision and press conference. Here I post the 8-hour EURUSD chart. Though it's the simpliest you can imagine, it can give you 2 significant clues.
1. There's a resistance line, starting from the end of August, 2011. Its current value is ~1.2680
2. Remember today's resistance pivot points: R1 @1.2648 and R2 @1.2698
Currently EURUSD tries to get over Aug.31 maximum level 1.2637. As we may expect an agressive decline during the conference time, I suggest being extremely attentive everytime if price goes to area, mentioned above.
Have a profitable trading!
