Bots on the ASX

Have been watching a certain share on the ASX today and noticed that at regular intervals (exactly every 5/10 minutes) small volume trades have been executed. There is also a (fairly) large buy order placed at a certain price point and the bot is obviously on the sell side selling. My questions are:
1. Who is that with the big buy order? Is that another bot?
2. What is the purpose of these small trades by the bot on the sell side? And is this a bullish/bearish sign for the share?

Here below are the trades for today up to 3:15pm:

Looks like an on-market crossing to me. http://www.asx.com.au/resources/crossings.htm

 

Are there any codes for an on-market crossing? Can't see any codes in the condition column to indicate these are on-market crossings.

 

Frome the website:

"In broad terms, on-market crossings take place as follows:

1.The broker places an order at the crossing price, i.e. the price they wish to cross at, then
2.checks that a crossing market exists. If not, they must create one. A crossing market is one where the priority buy price is one price step or less from the priority sell price.
3.The broker then places a crossing order. The crossing order immediately results in a trade where the broker sells to themselves."

At what point is the general public going to say enough of this mumbo jumbo BS!!

No idea.

I saw this happening with a stock I was watching a while ago for really tiny volumes of shares (like 7 shares @ 47.5c each). The next time I called my broker (ETRADE) about something I asked WTF it was because the transaction costs would have been more that what the shares were worth unless the people buying and selling had some kind of flat rate trading package. They said for those kinds of small trades the activity would be a crossing of some type where a broker is providing a sort of token notification to the market that they've facilitated a trade privately.

 

Very strange. Still can't see the reason why its done the way its being done. Even if they were token notifications or facilitated private trades why not in larger and more normal tranches and less frequently? Anyway I was too spooked by this afternoon's action and closed my position.

 

Its basically using algorythms to entice other algorythms
