i found some discrepancy between investing.com and the price from CME, as you can see below(red rectangle), the prices are different in 3 Jan 2019. for reference: https://www.investing.com/commodities/gold-historical-data https://www.cmegroup.com/trading/me...settlements_futures.html#tradeDate=01/03/2019 i have some questions below 1) do you know where the price from in investing.com? 2) if the gold futures price quoted in investing.com are from CME, do you know which time point is the last/settlement price quoted? As i know the trading hours in CME gold futures is basically 24hrs (1 hr break from 4pm). although the futures trade nearly 24 hrs, the price after evening may not be indicative, so i guess the last/settlement price should be right after the afternoon session? 3)can anyone tell me what is the difference and meaning between last price and settlement price? 4)when we talk about oil, we will use london brent oil and US WTI as reference, how about gold? which gold we use? sorry for my questions, i just want to make it clear because i am new in gold... many thanks!!
