Hav you considered this?, page-14

Well sought out Yskelo. I strongly suspect the position is larger as time delays in reporting is unknown.
I would imagine not all trades are fully reported... NOR ARE THE BOT trades..more on that later after research on brokers. IMHO any trade on DFM below 500 units, particularly on the down tic are a tool of such players found in 2 of the large brokers. Smaller brokers rarely entertain bots.

Some notes on short selling here
from the web
"
ASIC removed the ban on covered short selling of financial securities. Other changes will need to be kept up with and you can see the ASIC rules on short selling here. As a side note, covered short selling refers to someone owning the shares that you are borrowing. Naked short selling is when shares are sold without the consideration of where they are coming from. It is possible that more shares are sold than really exist.
Borrowed money and without ownership If you purchase a stock you own the shares. You can wait for 50 years to see if prices rise. As well, the money invested likely was spare cash. When shorting, you are trading on margin or borrowed money. This leveraged trading can often lead to bigger losses. As well, if the trade goes against you, it is closed out and you have nothing but a bad memory to show for it.
Is Short Selling Ethical?
Critics will claim that selling short will exacerbate a falling market. Some will view short sellers as the evil that pound a market down and prey upon the hides of a good companies misfortune. What is the truth?

1. Selling short does not mean driving a stock down without ever having to repurchase shares. You do need to cover the open position. The same could be said of irrational buying of shares. With a reduced float the stock is much more volatile and can shoot upwards very fast. But nobody complains since its ‘money for everyone’.
2. Short selling adds liquidity to the market. Imagine the frustration of trying to buy shares and nobody is willing sell. There could be a massive spread between the bid and the ask. Short sellers provide those needed shares and will close the trading gap.
3. Short selling creates checks and balances between company and shareholder. A short seller is actively looking for bad practices by management. We could even view short sellers as helping the ASIC keep on the watch for financial foul play.
4. Short selling is an important factor in fairly valuing stocks. Investors now have the ability to bring overpriced stocks down to more accurate valuation levels by short selling.

Selling first and buying back later is a legitimate way to trade. Both shorting and buying are fair practices in the market. Both can be carried out to the benefit of the market with the above noted advantages or both can be used in underhanded manipulative ways that give all traders a bad name."
