1. Fundamentals: judge whether the price of a futures contract is rising or falling.

2. Weigh risks and profit prospects: When speculators decide to enter the market, they should fully consider their ability to take risks. Only when the probability of profit is high can they enter the market.

3. Determine the specific entry time: the futures price changes rapidly, and the determination of the entry time is the most important. Futures speculators can think that in the long run, future futures prices will rise (fall). If the contract price continues to fall (rise) at this time, it may be that the speculators' judgment is biased and overestimates some supply and demand factors, thus making the price change deviate from the long-term situation.
