Lesson Learned: Not respecting the weekly close on CFD rollovers

Something I've come to appreciate, the hard way, is the importance of genuinely understanding how CFD rollovers are handled, especially around critical weekly closes. I had a position on $EURUSD open into a weekend where I expected a gap-up based on a news catalyst, but the CFD provider's rollover mechanism meant my position was effectively closed and reopened at a slightly different price. This wasn't a major slippage, but it meant my intended entry, based on the spot market's weekly close, was functionally negated, and the subsequent move I was anticipating happened from a less favorable basis. It was a good reminder that CFD mechanics aren't always a perfect mirror of the underlying, particularly for long-duration plays.
