Giusto a supporto di quanto dicevo sopra, ecco un breve flash di agenzia di ieri:

The three-month copper price slumped in afternoon sessions as algorithm trading drove down LME prices on Wednesday March 1.
Copper had been trading at $6,051 per tonne at 15:07 GMT, before sliding to $5,986 just two minutes later.
According to LME data feed, the vast majority of the business that went through during this period was just one lot a signal of
algorithm trading activity.
This is a key indicator that
HFT was behind the move. Smaller tick sizes provide the ability to move from one price point to the next,
usually at a speed far greater than a human trader could manage.
