Guidelines state the equal extension of 1 is the most common wave C; however, given the current economic environment, a 1.618 extension of wave A may be plausible target.
Given the swift breakdown seen yesterday, it is also plausible that we have commenced wave 3 of the greater wave C down, therefore opening up the possibility of the scenario shown.
1.618 extension would mark a -27.80% correction .
Not financial advice and always DYOR.
