Still kicking myself over that Stoxx 600 FOMO trade post-ECB

I let the post-ECB rally on the Stoxx 600 get to me last month, chased a move that had already extended, and then compounded the mistake by widening my stop just a bit as it dipped. Ended up eating a significantly larger loss than my initial risk model allowed for because I couldn't resist the perceived 'easy money' and then doubled down on the bad decision.
