Watching DAX at 18000 - a critical juncture

Been following the DAX pretty closely this week, and the 18000 level is really standing out to me. It's been acting as a psychological resistance for a bit now, but also seems to be garnering some support around there on dips. From a technical perspective, if we can establish a clear close above 18000 on a daily or even weekly chart, it could open up a path towards testing higher levels, perhaps towards the 18200-18300 range, which was a previous area of congestion.

The flip side, of course, is what happens if it fails to hold. A sustained break below 17900-17850, especially on increased volume, would be a strong indicator that the upward momentum is fading for now. My current thought is that a move back towards the 17700-17650 area would be on the cards if that support doesn't hold, potentially even filling a gap from a few weeks back. Always good to have these scenarios in mind, especially with the current macro uncertainty. I'm just observing price action around this area, not looking to jump in without further confirmation.
