Also curious to understand what happened there.. the order book...

Also curious to understand what happened there.. the order book at 3:59pm was like BUY ≈ 6,000,000 units SELL ≈ 4,000,000
Then as soon as the closing auction started, it jumped to like 20,000,000 units on both sides – it seemed wild (like usually there will be a few outlandish ghost bids/offers placed at the outset, but I hadn't seen it like it this, on both sides..) and they weren't ghost bids, but ended up being transacted.

I used chatgpt to crunch the day's data (lazy i know.. i did check a couple of the calculations, and they were accurate - but take with a grain of salt etc etc)... it doesn't really reveal anything to me, other than that a very large volume of shares were traded, esp in the closing auction - in a way that I would be surprised if it was not coordinated in someway among brokers (which i don't think is necessarily questionable.. they're on-market trades at the end of the day ig) anyway fwiw below
