Plotted are 3 different sets of Fibonacci Extensions. Each fib is like a "ruler" calibrated to a specific wave. Every level is relevant, especially the confluence zones.
4372.6 is the key level to break and hold as bottom marker. 4343.6 is immediate support that strong bull would hold. 4222-4224 is key support for bulls to defend as a higher low. 4073-4019 should have been the bottom and NOT be retested.
