Copper is a trading contract on the London Metal Exchange, and this price is the price traded on the floor during the day.

How did it come from? For example, you want 35,000 yuan to sell 10 ton of copper, and then the price of others is lower than yours. The price of others is 34,900 tons of copper, and the quality is the same, and the whole exchange has no lower price than him, so once someone wants to buy copper, he must trade with him, so once the deal is made, his trading price is the copper price you said.

This price is based on time priority and price priority.

Similarly, if you buy copper, then your money must be the highest price of all traders, of course, the timely price.

There is also an electronic disk, which keeps asking for prices like stocks at night. These prices are current futures prices.

Basis for the rise and fall of international oil prices:

The ups and downs of everything are related to supply and demand. If the supply exceeds the demand, the price will fall, and if the supply exceeds the demand, the price will definitely rise.

Oil prices are also related to political factors in producing countries, such as war.

When the United States attacked Iraq, the oil price should be very high.

There is also inflation. When inflation occurs, prices will definitely rise. There are alternatives, such as environmentally friendly alcohol fuels and so on.

The trend of the dollar is also related to international crude oil. For example, the Federal Reserve's $3 trillion purchase of bonds is equivalent to printing money directly to increase the direct supply of money. When the supply is large, it will naturally depreciate, so the dollar will depreciate. If the dollar depreciates, the price of gold will rise. Because gold has a safe-haven function, the depreciation of the US dollar will lead to an increase in international oil prices. Because money is worthless, things are more valuable. Crude oil is a practical thing. You might as well hold crude oil.

The relationship between the rise and fall of copper prices is more related to demand. Copper is used in construction, automobile, industry and so on. You think the subprime mortgage crisis is due to the bankruptcy of houses and car companies, and the demand for all copper has been greatly reduced, so the price of copper has fallen. Now that the world economy has recovered as a whole, the copper price has risen from 29,000 to 35,000 today.

There is also the question of whether today's price is the average price. Like stocks, today's price is today's price. Of course, this is the price of the forward contract. The copper price we are talking about now must be the price of the most active contract on the London Metal Exchange.

The copper price we are talking about today is 35,000, that is to say, copper 0906, the price of this contract. (Shanghai Futures Exchange CU0906 contract)

This price is the copper price predicted by most people in June 2009.

You got it?

Not the average price, the settlement price may be the average price, but all the rules of this transaction are probably the weighted average price of the last three hours. It's a bit like the average price of the stock in the last three minutes as the closing price.

It is estimated that there is a wave of market coming. At least this is a rebound.

What I said is not very professional, and you don't understand the professional. Give it to me for the sake of typing so many words.
