Position cost: the total transaction cost after trading a financial product or derivative (such as stock or futures) in batches for a period of time minus the floating profit and loss divided by the current holding quantity, that is, the position cost.

Similarly, the holding cost of etf is: the total transaction cost after trading ETF in batches (buying and selling) in a period of time minus the floating profit and loss divided by the current holding quantity, that is, the holding cost. The greater the floating profit, the smaller the unit position cost; On the contrary, the bigger.

At present, there is no gold ETF in China, but I believe that with the development of domestic financial industry, gold ETF will be launched in the near future. Now we can pay attention to other domestic ETF products.
