Imperial,

Then the bot is doing exactly what is supposed to! i.e. to not get spotted and not spook anyone.

Here are some examples which I easily spotted. They are spaced between 1m10s and 1m20s apart. Not sue if they are buys or sells, have to research more to find out. The trades on Thu and Fri that I saw were buys.

15:21:30 2,500
15:22:45 2,500
15:24:01 2,000
15:25:16 2,000
15:26:34 2,000
15:27:52 2,000
15:29:08 2,000
15:30:25 1,500
15:31:42 1,500

With time (and the inclination), you should be able to spot a lot more. It's all just noise in the trading day though so I wouldn't put too much into it!

ITG have some details here:

This is their US page, but they are also licensed and active in Australia so it would be safe to assume they are doing the same on the ASX; as are a number of other brokers.
