I use a sort of bastardisation of VSA and Wyckoff, and while two are very similar (VSA is derived from the actual Wyckoff Institute course),
there are some subtle differences, mainly in the way buying and selling are interpreted.
My Wyckoff side (mainly through David Weis) uses mainly wave charts, like the one above, and analizes the waves of the price action.
My VSA side uses bar charts, and analizes the individual bars of the chart.
And for the most part, each of the VSA terms for an individual bar, are also used in the Wyckoff wave analysis.
So a no demand bar (for instance), which is a narrow spread upbar, often closing in the middle, on low'ish volume, usually seen as a confirming indicator after weakness has already been seen.
Whereas a no demand wave is similar, as a shallow upwave with low'sh volume, usually seen after a rise in price, and where a trend maybe getting a bit tired, or something similar.
So quite similar, if you know what I mean.......
As an example, a VSA upthrust is an individual bar that looks like this-
whereas an Upthrust in Wyckoff, when referring to the wave chart in particular,
is looking at the price action, where price comes up to a resistance level and pops its head over the line and then fails-
(it doesn't matter what the shape of bar is- it is the price action in respect to the resistance level that is important)
So to recap, VSA is referring to the actual bar shape of an individual bar....."an Upthrust".
And Wyckoff, when using wave charts, is referring to the price action itself "upthrusting" a line of potential resistance.
