Wyckoff trading method, page-1150

I have a question for you Jako.

In relation to a high volume event, I remember you asking if the large volume was all on market (or part of large XT's).

Why does it matter? Is it because the XT trade is not a fluid reaction to the selling (its delayed and planned over a longer time frame)?

For example, CRB (gold exploration) is in a recent downtrend but if it were not for the large XT trade that went through the other day, you could argue that there was stopping volume. Is that right?

Thanks in advance, no rush.
