Because you can see is practicaly the same UP and DOWN and the time for UP and DOWN is also similar.
Then we need start in the next ascend February 9th , and put fibonacci reference there.
Then we can see that 0.382 Fibonacci is very important linea of resistence
and determine if stock market get over a new historic level.
But if stock market dont break trought this resistence line (2753-2757) then it can drop to 0.618 fibonacci.
We see what will happen today, Monday.
