The P/V momentum this week was not strong enough to confirm the DAILY UPTREND.
The UPTREND that started on Nov 2, 2017 is still continuing- for the seventh session - regardless of today's 16.28% decline in share price.
The metric integrates price and volume momentum to confirm any trend (up or down) when it first shows up in the daily. Then, it either gets confirmed (or not-confirmed) by the weekly. It is held at a higher level to help prevent frequent changes or flip-flops in the signal, from share price 'ripples' of smaller magnitude. We shall see next week how it unfolds. GLTA
