How did I figure this out? It's pretty simple, actually: you "look at the chart" and watch the order book. You do have level 2 quotes, don't you? Everyone who is a "serious" investor has them, right?
WIN did "bust through $8.80" (again, look at the chart) shortly after my post. You can see the uptick and down tick volumes by minute (close enough for this analysis). And then it came right back and closed below $8.80.
Tomorrow will likely be a different story but TODAY there was resistance as the price approached $8.80.
