1st scenario
Wave iv ends at the bottom line of the triangle, line that almost coincides with the whales support. New impulse wave that completes the wave v of larger degree, which at the same time completes the wave (v) of one larger degree more.
2nd scenario
Wave iv breaks the bottom line of the triangle, ending near the 52.6k level. New impulse wave may be a truncated fifth (wave v does not move beyond the end of wave iii).
