Let me tell you, unlike futures and stocks, the bank’s paper gold and silver is a market maker mechanism, which means that the bank bets against you. The spread is mandatory and must be charged to you. 4 cents/gram, you are right to understand it as your transaction cost
There is no spread in futures, only handling fees. The handling fee for 15kg of silver is only a few yuan, while 1kg of silver at the bank costs hundreds of yuan. , you can calculate whether the handling fee of several hundred times is a scam. Paper silver will lose money in the short term, because the profits from short-term fluctuations are not enough to pay him the handling fee.
Futures are of a matching nature. Buying and selling are done between customers, and there is also a price difference. The buying and selling price difference is 1 yuan per kilogram, which is equivalent to 0.001 yuan/g. This price difference is caused by the matching between buyers and sellers and can almost be ignored. Don’t count. Have you ever done it in stocks? There is always a very small gap between the buying price and selling price of the latest level. The principle is similar.
I am from a futures company. If you are interested, you can learn about futures. However, the minimum price for silver futures is 15kg per lot. Please pay attention to whether you can bear the corresponding risks.
