"The before and after "auctions" on the ASX plus algorithmic trades throughout the day place small investors at a disadvantage. The banks broking arm use the knowledge they have regarding my holdings and my orders to feed into computer trading where the computer can make a small trade milli seconds prior to close that can alter the final price. I try and alter my trade minutes before closing only to find my order "referred" and not acted on before closing. I have been left with an order partly filled with ONE share and paying full brokerage on that transaction. If the SP rises, as it has, then the bulk of the order is not filled.
Bot trading throughout the day is used to manipulate the SP on many occasions. So obvious it must be intentional.
The answer should be;
1. No auction before or after trading hours.
2. All trades should go through in the order they are placed. (no queue jumping.)
3. Orders should not be "referred" without a valid reason.
4. There should be severe penalties for attempted market manipulation."
