If Fibonacci number is used, then, wave structure may be 8, 13, 21 wave legs.
If TD sequential number is used, then, a wave structure can get 9 or 23 wave legs.
It is no need to twist any price structure into a 5 wave structure with many sub-structures, which seem make Elliot wave theory or wave counting as a pseud science / theory.
Natural and simple wave counting is the better method, I believe.
