My biggest CFD mistake? Chasing a breakout

I've made plenty of errors over the years, but the one that still stings from a CFD perspective was chasing a perceived breakout on a $DAX30 index CFD a few years back. The setup looked solid on the daily, had a clear resistance level, and volume was ticking up pre-market. Got in right on the break with decent size, only for it to immediately reverse, take out my stop, and then actually run higher without me. Classic head-fake, and I didn't respect the volatility enough to either wait for confirmation or size down significantly on the initial entry. It taught me a hard lesson about the difference between a real breakout and a liquidity grab on a high-leverage instrument.
