London silver refers to foreign silver, which is in line with the international and foreign silver markets. The price of silver is quoted directly in dollars. This is a kind of spot. 24-hour continuous trading, leverage 100 times. The risk is very high. At present, foreign silver platforms belong to the gray area of state management and may be banned at any time. The difference between futures and futures is mainly the difference in transaction time, transaction cost and platform regularity. Foreign silver trades 24 hours a day. Futures are traded for three time periods a day, and the leverage of external silver is 100 times, which is risky, while the leverage of futures is generally around 10 times, which is relatively less risky. The handling fee of foreign banks is high, which is generally about 20 times that of futures. As for the platform, the foreign exchange platform and the futures platform are incomparable. The difference with paper and silver is almost the difference in these aspects. The difference is that paper and silver can not only buy up, but also buy down. Futures and spot can be traded in both directions, and both can buy up and buy down.
