Thank you for your response, Grey1.
On an empirical, logical and rational basis, when selling/shorting slows down, the probability of consolidation and/or reversal increases.
I am not suggesting that there is some sort of significant or measurable "slope" which should be used as some sort of parameter, what I am saying is that actually reading, (as in tape reading), what is happening and marrying that with TA leads to a much higher probability of accurately assessing an imminent move.
I assume you would agree with the caveats I mentioned about volume.
I'm confident you would agree with me that the markets are multi-factorial and dynamic and over reliance on a single element or technique can lead to over simplification and distortion.
I do in fact broadly agree with you, but your statement,
"Falling price along side falling Volume should be seen as sign of strength than weakness" would, perhaps, have benefited from a little clarification.
Please don't think that is meant in any way as a criticism.
Far from it.
I'm sure there are quite a few occasions in the past when I could have explained things better ;-)))
