Judging from the daily chart and the longer time frame chart, the whole tin futures showed an obvious upward trend, and there was no confirmation of any turning signal. From this perspective, the upward trend will continue, and it is bullish to some extent. But from the overall price point of view, tin futures have risen for a long time, and the price is already in a very high position. From the global situation, the next policy tends to shrink liquidity, which is a negative factor for major commodities, that is, commodity futures prices may fall in the future. Therefore, in the short term, there is still room for tin futures to rise, but in the longer term, especially from 2022, tin futures prices may turn around and fall. Everything depends on when the liquidity contraction policy is implemented. Of course, the preparation time is not easy. You can wait until the trend is clear, then consider opening a position.
