I got it.

"AT 4pm, the market enters what is known as ‘Pre-CSPA’ (Closing Single Price Auction).Between 4:00pm – 4:10pm, orders can be entered into the market and existing orders can be amended. We have a similar situation to that of the Pre-Open phase. It’s handy to know of this period, as some investors I’ve spoken to just after 4pm, who are very keen to either buy or offload some shares that day, think it’s too late for them. And yet, they can still buy or sell if they get in by 4:10pm.The final ASX closing time At 4:10pm, we have the Closing Single Price Auction, where the algorithm applies again to determine the closing auction price at which any overlapping orders are matched off against each other."

ZIp had a flurry of action in that time period on close today. Thanks.
