Only volume traded. I still sense a lot of dip-buying. That will tell the most. Sure, as long as the stock trades TA can be helpful. It's a high vol reversal from a downward trendline.
Most people avoid the opening.
Of course, that's exactly when I DO buy. My two daughters control all music in the house and car. Have not used them. They usually follow us. A fund that has discretion to go long and short.
