can anyone explain or speculate on this?

I'm pretty sure others have noticed by now as it has been going on for months - often AOE and ESG have the same aftermarket trades - give or take.

For example - today after the close :

ESG

05:08:44 PM 0.770 14,390 11,080.30 XTSXOS
04:53:19 PM 0.770 14,390 11,080.30 XTSXOS
04:53:19 PM 0.770 14,390 11,080.30 XTSXOS
04:49:20 PM 0.000 0 0.00 XT
04:31:15 PM 0.770 14,390 11,080.30 XTSXOS
04:30:48 PM 0.000 0 0.00 XT
04:17:03 PM 0.770 2,890 2,225.30 XTOS

AOE

05:08:42 PM 3.650 14,385 52,505.25 XTSXOS
04:53:18 PM 3.650 14,385 52,505.25 XTSXOS
04:53:18 PM 3.650 14,385 52,505.25 XTSXOS
04:49:20 PM 0.000 0 0.00 XT
04:31:12 PM 3.650 14,385 52,505.25 XTSXOS
04:30:45 PM 0.000 0 0.00 XT
04:21:00 PM 3.540 11,511 40,748.94 XTSXOS
04:17:00 PM 3.540 2,889 10,227.06 XTOS

This is a very regular occurrence - guessing they are computer generated trades - but why ESG and AOE.

Anyone?

Here's one I'll get shot down for - STO buy both AOE and ESG and then Shell swallow STO for there 16MTPA plant.
