First of all, understanding the market trend is the primary task of stock index futures. Investors must continue to pay attention to the changes in the market and implement trading strategies by analyzing historical data and trend prediction. Only when the market trend is clear can we accurately predict the future price changes. In addition, it is also important to understand the influence of economic, political and social factors on the market. Investors must always be vigilant and constantly update their knowledge and understanding.

Secondly, mastering risk management skills is also a key element to successfully do stock index futures. Stock index futures are high-risk investments, so many investors will lose money. Mastering correct risk management skills can help investors reduce risks and improve investment success rate. Some effective risk management strategies include limiting the investment amount of a single transaction and setting a stop-loss price. Investors should make their own risk management plans according to their own risk tolerance.

Finally, a stable mentality is also a key factor in doing stock index futures. The emotional reaction in the decision-making process and trading will significantly affect the performance of investors. Greed and fear are the most common emotions of investors and need to be controlled. Investors should follow their own plans, don't blindly follow the market, stay calm, set reasonable expectations, and learn to accept losses. Only with a normal mind can investors succeed in the stock index futures market for a long time.
