On higher timeframes, wave (B) may develop as part of some big correction, which, for example, may take the form of a FLAT.
On the daily chart is very clearly visible triangular structure. In the basic version, it could be completed and the upward movement will continue in the third wave. Alternatively, the last wave of the triangle will continue its development.
On lower timeframes, the latest downward movement resembles a double zigzag that can already be completed as part of the second correctional wave.
