Warning: Don’t do HFT on the Oslo stock exchange!

On my way home from work today, the front page on the news paper Dagens N√¶ringsliv caught my attention. It says “Tiltalt for √• ha lurt aksjerobot”, which translates to something like “Prosecuted for having fooled shares robot”.

So what is this? Socialism on a stock exchange? Poor bot owner, who had a non-optimal sub-performing algorithm that lost them money? Or are the people at Oslo stock exchange just not getting high frequency trading, or not liking it? Or are they loving the high volume that algorithmic trading might bring them so much that they try to protect the big fishes?
