    Obviously bots at play. Interesting ASX response in regards to a bot query on AVX which was posted by Mrmoshe. I have copied his post below. Looks like bots ain't going to stop.

    "Well, after lodging a complaint about the robots to the ASX, they have done their investigation and confirm that DMA (Direct Market Access) (read robots) were active during the period I complained about.

    Problem's all above board and the ASX doesn't think it's a problem.
    Looks like we are stuck with robots forever.sigh!

    Below is the ASX email to me:"

    Dear XXXXX,

    Thank you for your email.

    Having reviewed the course of sales data for AVX for February 18 and 19 it appears the trades you are referring to, are the result of DMA (Direct Market Access) or algorithmic trading.

    You may be aware that DMA trading allows a client to send orders directly onto a trading platform without human intervention. One form of DMA trading involves a strategy to match the volume weighted average price (VWAP) for a stock over a day. As a means of capturing the VWAP, a single order might be split up into several smaller orders which are
    submitted periodically (every 3 minutes for example).

    This type of DMA trading is normally unremarkable and has no impact on the price or volume of a stock. However, occasionally market observers may see small volume orders being submitted to a trading platform in a less liquid stock which result in small volume trades.

    Surveillance monitors DMA trading and expects brokers to have in place appropriate mechanisms to ensure that such trading is not manipulative.
    DMA trading is an increasingly popular means of trading, particularly when a participant seeks to track VWAP or 'slice and dice' an order for other purposes. Further details and articles regarding DMA trading can
    be found be searching under "DMA Trading" on the ASX website. Please refer to the link below.

    Please be advised that ASX surveillance has been notified of your concerns and will continue to monitor the trading in AVX.

    I hope this is of some assistance to you and I appreciate you raising your concerns with ASX.

    Kind Regards
