Hi Eric,
Concerning the quotes - we've talked about it millions of times. I trade futures on EUR/USD, so my quotes a bit different, but as you understand all swings and patterns looks similar to spot. It couldn't be other way. So, to estimate the same level, that I use, but on spot you should make the same work as I do, but on your own chart. This will be prudent.
Second, about the signals. I think you're right - there is no solid reverse patterns, except may be Hammer on hourly chart. But, as you remember - 1.4050 area (in my quotes) was - pivot, 4-hour Confulence and Agreement. This combination itself is a signal.
If this is too dangerous for you - I understand that, this is wise. Then - you may try to enter on retracement. There is no tradegy, that you've missed the low. Wait for pullback - and come aboard. But never jump in running train...
Always think first - where you will place stop. And only after that search for entry level.
And the last one - if sometime, you do not see any signal (as in our current situation) - look at trend. When you've seen that market has hit important level and target, and then all trends have turn in your favor - wait for nearest pullback and enter.
