1. Try to open positions after significant drops or rises. 2. Go long after a significant drop and go short after a significant rise. 3. Try to choose contracts with a longer duration; otherwise, the market may move before the contract expires, and even if you open a new position, it may either lead to sunk costs or increase the cost of holding. 4. Ensure you have sufficient margin. 5. Within the contract's validity period, you can also engage in high selling and low buying. When in profit, appropriately reduce your position size; when losses are larger, you can make up for it. This way, you can lower costs while increasing the margin ratio, all within your current funds. 6. Provided the margin is sufficient and the position is moderate, as long as the favorable direction hasn't changed and the contract is still valid, the best approach is to let it rise and fall—just lie down and play dead. 7. The biggest risk of a contract is primarily that the margin is insufficient to withstand volatility, leading to liquidation; secondly, a short remaining duration loses future potential, causing predetermined losses; and lastly, betting in the wrong direction can result in irreversible losses!
