I hope you are well. Please add the “NYMEX GOLD CHART “TO THE London Gold chart. The price difference sometimes is significant like yesterday. The Nymex close was approx.. US$ 20 higher.

Thank you for this question which may be of interest to subscribers. The London Gold fixing reflects spot prices whereas the futures prices are traded on NYMEX. The current on the run futures point at December so it is not unreasonable to expect a difference in pricing.
Here is a chart of the spread over 20 years. There have been occasions where it spikes on supply shortages in the physical market but spends most of its time in a narrow range.
