The weighted average method is the basic method of index synthesis, which has two forms, namely, the addition rule and the multiplication rule. The weighted average method is also called "comprehensive weighted average method" and "monthly weighted average method". Inventory cost is a method to calculate the weighted average unit cost of inventory, based on which the cost of issuing inventory in one month and the cost of ending inventory are calculated.

Application in futures

On the one hand, if the futures price is higher than the weighted average, the latter is moving up slowly or rapidly, which indicates that the market situation will be easy to rise but difficult to fall or continue to improve. On the contrary If the futures price is lower than the weighted average, the latter is slowly moving down or rapidly moving down, which means that the market situation will be easy to fall but difficult to rise or continue to fade.

on the other hand, if the futures price is higher than the weighted average efficiency, the latter is running in a narrow range or moving down. That is to say, the market situation will slow down or turn around and fall back. On the contrary, if the futures price is lower than the weighted average, the latter is running in a narrow range or moving up, which means that the market situation will slow down the decline or turn around and pick up.

the reason is that the futures price cannot be supported by the same moving direction of the weighted average due to the uptrend or downtrend, and the space for re-launching or re-falling will become limited. It should be noted that the weighted average will pull the futures price and prevent its increase or decrease from expanding.

therefore. At the same time, we should also pay attention to the change of the gap between the futures price and the weighted average, and observe the opportunities of entering and leaving the market when the gap is too narrow or too wide. If the market situation is still rising or falling, the phenomenon of too narrow gap can provide a good opportunity to make the market better or worse. On the other hand,

even if the market is still in the process of rising or falling waves, the phenomenon of too wide gap can provide a good opportunity to make a small note of the market against the trend. Finally, we must remember not to rush into the market against the trend to make it weak or good just because of the huge cumulative increase or decrease in futures prices without calculating the upward or downward movement of the weighted average at the same time.
