My first big lesson: The moving stop loss

Hey everyone, just joined. Been around the block for a few years now, mostly in FX and dabbling in a few large cap stocks. My biggest lesson, one that still makes me wince, came early on with a EUR/USD long position. I had a clear target and a stop set just below a key support level. Everything was going according to plan, price moving nicely in my favor.

Then, as it often does, the market had a minor pullback. My stop was still holding, but I got antsy. Decided to "give it more room" and moved my stop further down, just a few pips, but enough to breach my original risk management. Sure enough, it wicked down, hit my new wider stop, and then immediately reversed and shot right back up to my original target. Cost me a decent chunk of change and, more importantly, a lot of confidence in my initial analysis. Taught me to trust my entry and stop placement. If the setup isn't valid with the original stop, it's not valid at all. Haven't moved a stop against myself since.
