SPX's Elliott. What if, and only if, the whole count is FLAT !

Flat Rules:
A Flat is a three wave pattern labeled A-B-C that moves generally sideways. It is corrective and counter-trend and is a very common Elliott pattern.
Wave A can be any corrective pattern except a Triangle.
Wave B can be any corrective pattern except a Triangle.
Wave B must retrace more than 70% of Wave A.
Wave B is less than twice the price movement of Wave A, including internal points of Wave B.
Although there is no minimum time constraint for Wave B, it must be less than 10 times Wave A.
Wave C must be an Impulse or Ending Diagonal.
Wave C must share some common price territory with Wave A.
Wave C must be less than twice the longest of Waves A and B, including internal points of Wave C.
Wave C must be less the three times the price distance of Wave A.
Disallow back to back failures.
Wave C must be no more than 10 times either Waves A or B in price and time.
There is no minimum time constrains for Wave A.



Flat Guidelines:
Wave A is usually a Zigzag family pattern.
Wave A is rarely an Expanding Triangle.
The largest Wave within Wave A is usually less than Wave A by price.
Wave B is usually a Zigzag family pattern.
Wave B is rarely a Flat.
Wave B is usually greater than 95% of Wave A by price.
Wave B is usually less than 140% of Wave A by price.
The largest Wave within B is usually less than Wave A by price.
The time taken by Wave B is generally between 61.8% and 161.8% of Wave A.
Wave C is rarely an Ending Diagonal.
Wave C is often about the same length as both Wave A and B.
Wave C often ends at point which is a percent of Wave A beyond end of Wave A equal to the same percentage away from the start of Wave A.
Wave C usually retraces a minimum of 100% of Wave B.
Wave C normally reaches to the end of Wave A
Wave C is not often more than 140% of the longer of Wave A or B.
If Wave C is longer than Wave B, then Wave C is often about 61.8% of A beyond end of A.
If Wave C is longer than Wave B, then Wave C is often about 161.8% of Wave A from end of Wave B by price.
The time taken by Wave C is generally between 61.8% of Wave 1 to 161.8% of the shortest of Waves A and B.
