Wyckoff trading method, page-1223

I think the supply vacuum bar might have been the bar immediately after the shakeout, the upbar on low volume.

Looks like a pretty serious shakeout which dipped below previous support, then a low volume response that confirmed it contained buying.
Following that is a (bit messy looking) mini shakeout or high volume test, which finally closed higher after dipping down below the previous bar's low.
Then a tiny upbar on no volume, and then a serious markup of price.

After having a quick look at it, I won't be surprised to see price come back and test the seventy cent level for supply, and I also note a little gap was left behind when price accelerated away......I haven't had a look at what has happened today yet.

cheers
