tjwny, "Hurst is a price based system and price is the only variable;........."
Hurst uses time. cycles are time. price (amplitude) is determined by the cycles. variation in time cycles and in cycle amplitude is caused by fundamentals. sudden increases in volume indicate a fundamental interaction. they are not predictable.
are you saying vector vest predicted the size and speed of the decline or that a decline was possible? Hurst phasing indicated a 20 wk cycle low was due around now. it did not suggest the size of the decline until the 20 wk fld was crossed. that gave a price target that on a closing basis has held. has vector vest given a price target for this decline?
