QuoteMedia Spot Metal Markets (excode SPMTL) data is derived from continuous spot selling prices at banks in countries where spot markets exist, aka from realtime trading of currencies just like bills/notes.  It is not a future, although pricing can sometimes align closely.

Trading hours are based on banks hours which globally are 24 hrs, 24:00 to 24:00 GMT/BST.  We create a "close" value at 01:00 GMT/BST or 20:00 ET.  (Note: The market does appear to be closed for one hour on Sundays and trading on weekends is light.)

QuoteMedia's CME (markets) continuous futures are an alias to the most current leading futures month at any given time. They are futures, not spot prices.  Some publications use the CME data as representative of the 'current' price of some commodities. They may have similar pricing/trends but they are not the same.

We have Level 1 Real-time data available (no Level 2).  Historical data for some symbols goes back to 2006.
