First of all, let me talk about what is the gold price difference. Gold spread refers to the difference between the buying price and selling price quoted by gold market makers to market participants. There are two forms of price difference in gold trading: the first is for gold market makers. Usually, the gold market maker will quote the buying price and selling price to the market participants, and this buying price and selling price are different from the gold price in the international market, which is the price difference. Gold market makers must unconditionally buy gold that other market participants want to sell according to their own buying quotation, but they must sell gold to buyers who want to buy gold at this price according to the selling quotation. Brokers also have spreads. When a brokerage firm charges a trading commission, it is charged not according to a fixed amount but according to the number of transactions, such as per gram 1 yuan.
Second, the price difference is the difference between the buying price and the selling price. The smaller the difference between the buying price and the selling price, the smaller the cost for investors. After long-term trading, the spread has a great influence on the overall profit and loss of short-term investors, but has a little influence on medium and long-term investors. Take Euro/USD as an example: the buying price 1.4390 and the selling price 1.4393, and the difference between the buying price and the selling price is three points. If you want to buy the euro at this time, you can make a deal with 1.4393, and the profit and loss show three points, that is, the loss value is -30 USD (3*$ 10=$30). The loss of 30 yuan can be regarded as the cost of opening a position. In fact, the spread is the cost of our transaction, which is almost the only transaction cost in foreign exchange market transactions, equivalent to the transaction fees charged by brokers in stock trading.
I hope my answer can help you!
