I want to ask, which broker has the smallest spread for gold?
I think you could try it at Octa broker.
The way to find out the gold spread of a broker is to look at the Trading Conditions or Instruments page on their website. There you can see what spread is provided for gold and you can compare it with other brokers. Here's an example of looking at the gold spread at Octa broker.


For other broker options, you can also see references at Brokers with Low Spreads for Gold Trading.
Thanks
@abi: Please check the gold spread comparison on the official broker page. Some brokers that specifically have small spreads for gold trading are listed here.
Thank you
