If we can make new highs above the box, this will mean most certainly the confirmation of the B wave. try to look for shorts in the area of the B.
if we can however make new lows below the white box then i think another impulse down is likly.
note: another impulse down first would ofc . mean alot more time spend in this correction while a confirmation of the B wave would mean the would be finished alot faster thought this year.
if you need a reason to go short below the decession zone. you could take this head and shoulders pattern
if you need a reason to go short at the B point you can take this shark pattern PRZ right at the 618 retracement.
