Lesson Learned: Moving Stops on $EURUSD

It's always the same story, isn't it? I remember a particularly painful $EURUSD trade where I had a tight stop, reasonable given the volatility. Market dipped, almost hit it, so I 'helped' it a bit, moved it just below what I thought was the new support. Of course, it wicked through that, stopped me out, then promptly reversed and rocketed in my original direction. Cost me a solid R and the mental game for the rest of the week. Never again.
