Are you asking why there are so many transactions of various sizes all at the same time?

If so, it's the closing auction. All the overlapping bids and offers are settled at the same price. Between 4:00PM and 4:10PM orders are accepted on the ASX market but they are not executed. At 4:10PM, if there are any buy orders where the buy price is greater than or equal to the sell price of any sell order, the auction is conducted as follows:

1. The highest-priced bid (buy order) is matched against the lowest offer (sell order). The result is that the smaller of the orders will be fully executed, and the balance of the larger order is carried forward.
2. Then next next order is taken and matched in the same way.
3. The process repeats until the highest remaining bid is below the lowest remaining offer.
4. If there are multiple orders at the same price level, orders that were placed earlier will be executed ahead of later orders.
5. Whatever the price was of the last matching orders, that is the price applied to all the shares exchanged in the auction.

What you are seeing in your list is all the trades generated in the auction. The numbers are weird because one order might only have a handful of shares left over after the previous match. In the next match those few leftovers are executed and then the next order is processed.

Are you an individual investor trading on the ASX by yourself? You really need to understand how the market works or you're going to get caught out frequently by the things you don't know.
