Support & Resistance Level on US 10 Year Treasury - Weekly Chart

On this Weekly chart I add the lines of key support and resistance levels for the US 10 Year Treasury. It's at a pivotal point right now hovering around 4%. What i'm watching for is to see if it's going to reclaim 4% for 2 consecutive weeks at a minimum and move higher to re-test that 4.25 to 4.28 range or if it will stay below 4% for 2-3 consecutive weeks and move lower into the next level down that I have marked off with white lines. I watch this closely as I am in the mortgage business and what the 10 year does daily will impact mortgage rates.
