Market-On-Close (MOC) Orders? Limit-On-Close (LOC)?

what are those massive orders that always happen right in the seconds or sometimes minutes after market close?


below is a photo of one of thise huge orders as seen from the time and sales tab in ToS.

most of the time is two of these either red or green both and always at the same time.

you would see 1, 5, 10, 200 shares and then boom...one day is two of 280,000, or 105,000. today was two of 405,493. (photo only shows one cause i was slow)


AND MORE IMPORTANTLY....how can we get a sliver of an edge with this info? if its a green order of 500,000 on a stock that usually has a closing order of 100,000 and a daily vol of 1,500,000 shares, DOES THIS MEAN LARGE BUYERS ARE GETTING IN AT MOC?

thanks!
