Not big. Futures interlocking refers to the continuous daily limit or daily limit in the futures market. In the case of interlocking, many factors need to be considered, such as market conditions, supply and demand, capital flow and so on. Although the futures market has certain volatility and uncertainty, it is not common for futures markets to be linked. Under normal market conditions, futures prices usually fluctuate, rise or fall, rather than continuous daily limit or down limit. Therefore, the probability of futures linking is very small, not big.
