Wyckoff trading method, page-1642

Ummm, it is more of a visual thing for me, and after seeing hundreds of charts over the years (or more), I sort of know what to look for.
Maybe I'll try to put up some examples over the weekend, if I get a chance.

On that chart you posted, price was initially going sideways, then it dipped sharply lower.....which to my eye was more like a shakeout at the end of an accumulation zone (a slow motion shakeout, over a few bars, if you like).
So firstly price came off sharply, then almost the entire offer stack was probably bought (on that upbar you marked as a breakout), then price came back and tested for supply for a bar and a half, and then it accelerated away.
This may have served the dual purpose of a final accumulation before a breakout, and also to remove a heap of supply that would have sold into a breakout, and made it more difficult (and expensive) to push higher.

(so as long as this is no pump and dump, or a pump for a CR or something)
If the supply is not overwhelming in the future, price may successfully be marked up , but if supply becomes overwhelming (or too expensive to absorb), it will most likely come back into the previous range, and the retail traders will probably call it a false breakout or something.....(haha).....
But it does show some 'intent', or a want to move price higher......and next, most likely, will come some further absorption of supply within the trading range, and/or another shakeout or two, in an effort to remove more of the supply above, to clear a path for a sustainable breakout.....before another breakout is attempted.
