The usual coverage of HFT on ZH is like this:<p>Gold price spikes down, it&#x27;s the HFT slamming it because they work for the Central Banks. Gold price spikes up, it&#x27;s because investors are concerned about the market.<p>Stocks spike up, it&#x27;s the HFT again. Stocks spike down - investors start seeing that the whole market is a scam.<p>So the HFT trade only in the &quot;wrong&quot; direction according to ZH. They sell gold and buy stocks. Never the other way around. I&#x27;m exaggerating, but only a bit, there were a few articles which blamed HFT for &quot;right&quot; moves (gold up, stocks down).
