I definitely agree that having levels of access to the asx available for a price is unfair, that system makes money for the asx precisely because its designed and priced to exclude large segments of the investing market.

But if we believe that the falling price can be blamed on bots here is a winning strategy:
When you see bot action to the downside, sell everything immediately. The bots will happily smile to themselves believing they have hit someones stop loss and start selling to the next price level in hope of triggering more. But its none other than yours truly waiting there with the buy orders! Rinse and repeat.

Obviously this can't work all the time, or the instos would be losing money fast due to their predictable intentions. So there's something more to the SP weakness than just bots....
