Session time confusion

Good Evening folks,

1.This might seem very basic, but I want to know what is considered as intra day session times? Should those be set to (PST) 6:30 - 1:00 (or) 6:29:59 - 12:59:59 or what is the correct combination. The reason is, I am looking at NVDA, there seems to be massive volume spikes at specific prices at session start and mostly session end around 1pm.Attaching a screen shot for reference. This affects the POC and it looks very suspicious and I am wondering if I am doing something wrong.

2.Along with the same question, What are the massive orders that show up at 1pm immediately at/after close. For nvda specifically they are almost 20 to 30million showing up everyday right around close. Are these dark pool transactions getting reported?

Thanks much!
PS: Screen shot is for range candles. But the volume profile looks same for time candles too.

Charts for stock symbols will already have the correct Session Times and they do not need to be changed. They are 09:30:00 Start to 15:59:59 End. These are US Eastern times.

We cannot answer any questions about volume.
