Precious Metals can be bought when the Loco London Precious Metals Market is open and there are trades in these metals. Regular trading can take place 24 hours a day from Monday to Friday (London time)
Loco London Precious Metals Market has its own holidays during which they are not open for trading. These depend on the public holidays in the UK and USA (https://www.lbma.org.uk/prices-and-data/value-dates ).
Currently, we do not provide trading outside of regular trading hours.
