GBPUSD: cable running away to the downside

Cable is likea runaway train right now. Price continues lower without an answer.
the price broke support at 1.2772,
and we are ending Friday with new the lows.
This all looks fairly bad for cable right now!

The extended decline this week fits a third wave scenario.
If wave 'iii' of (iii) is now underway,
then the declines should continue early next week,
and trace out a clear five wave pattern in wave 'iii' black
