The EURUSD 1.0700 level and my Waterloo

Thought I had the EURUSD breakout above 1.0700 pegged perfectly. Felt confident the retest would hold and we'd be off to the races, so naturally, I sized up a bit. Lo and behold, the 'retest' turned into a full-blown dive right through my stop, then lingered around the level for the rest of the day, teasing me with the possibility that I was right, just early. Lesson learned (again): conviction and oversized positions are often a disastrous pairing, especially when you're convinced you've found the 'perfect' setup.
