First of all, it should be clear that futures contracts are time-limited, such as ru 170 1, ru is rubber, 170 1 yes 17 1. If there is no spot trader to hedge the futures contract, it must be closed before delivery, usually one month in advance. However, there is a price difference between contracts in different months, and it is costly to change contracts into months, which constitutes a huge obstacle in the long run.

Then let's talk about a very common phenomenon in futures: overnight gaps. Overnight gap can be understood as a significant gap between the opening price of the night session and the closing price of the afternoon session, or as a significant gap between the opening price of the next morning session and the closing price of the previous day. However, the gap is sometimes fierce, such as 500 points at a time (the margin of a single rubber contract is generally 10000 ~ 20000500 points, that is, the net profit and loss of a single contract is 5000 points), and a reverse gap may be directly out. This, in turn, constitutes a long-term obstacle.

So intraday trading is more secure. However, the exhaustion of huge profits takes time. If there is a reliable risk control strategy, we can make a trend.
