Future forecast: In February, the global refined nickel dominant inventory is still at a historical low, and the price rise elasticity is relatively large under the status of low inventory and low warehouse receipt. At present, the nickel futures price is still dominated by the capital game. Before the apparent recovery of the dominant inventory, the nickel price may still maintain a high and wide fluctuation.

　　Key points of analysis: the price of propane on February 6 fell by 2.72% compared with the price of the previous trading day. The international oil price has been lowered one after another, depressing the market mentality. At the same time, the market of liquefied petroleum gas (LPG) was weak, and the recent increase in the supply of propane at the port, the accumulation of on-site inventory, the performance of the downstream demand market was depressed, and the price of propane dropped from a high level.

　　Future prediction: the supply side has increased significantly. In order to stimulate the purchase of goods, it is expected that propane will still have downward space in the short term.
