Well, it WAS a Friday, so I don't blame yourself too much. It's one of those HTF bits that it was up to.
1.7110 has been there rolling Support for 2 weeks. 1.7040 is the next lower HTF Key Support & Order Block collection. Friday appears to be several major players just unwound a massive amount of their Sell Positions, and possibly flipped them, but we'll see.
I think everyone was surprised that happened on a Friday. Though it was a little funny to watch it bounce between levels on the chart for a few weeks.
