Following Trump's statement about talks with Iran, $270 million in shorts were liquidated. Total liquidations over the past 24 hours reached $800 million.
It looks like manipulation and another attempt by Trump to "save the stock market" and push oil prices lower by creating the impression that everything is under control and that "we've won" - something he has generally liked to do throughout the past year.
Meanwhile, Iran's Foreign Ministry denies that any talks with the US took place and accuses Trump of trying to buy time.
