Price is at the neckline. Long entry would be a break of the neckline with an uptrend. I would imagine DG is getting a bit tired and is having issues at the neckline.
I think it will push through but not unusual to take a few tries. Sometimes hard resistance can knock a security back down.
Any pattern can fail and a double bottom can become a triple bottom )o:
You can measure bottoms by drawing a line from the bottom to the neckline. Then extend it up from the neckline using the magnet. This is a ball park guesstimate of where price may go.
As a rule, with a multiple bottom structure, you place a stop under the bottom. This is a tall structure making the stop too far away. I usually use the last pivot low when that happens. For me that is under 192.
