SQ with the check mark bottom. "Checkmark bottom" is what we've discussed where the largest buyer simply removes their bid for a few minutes letting the shares drop down before coming in hard. The fake out move likely scares a lot of day traders and weak holders so I go in hard with big options when I see that move recover to pre-checkmark levels.
Sorry it is SQ not BOX
Here is what you wait for. All the dips and recovery had no mass volume. Then this quick one had over double the minute volume. THAT's the one you're looking for. Then note it races away from the days lows. Whether that ends up being an intraday reversal or a trend reversal remains to be seen.
