The first step in formulating stock index futures investment strategy is to recognize the trend and determine the basic direction of trading. Then through the previous trading data, such as K-line combination, important moving average, trading volume, positions, etc., several key resistance and support positions close to the current price can be determined, and generally three or four key positions can be set.

First of all, this position can be used as a stop loss point or as a stop loss point at the current position. If the actual price trend is inconsistent with the previous judgment and there is no strong rebound after falling below the key support level, then stop loss can be considered. Similarly, after the price breaks through the key resistance level, it is unable to challenge the next high point. At this time, you can consider profiting from liquidation.

Secondly, the key position can be used as a reference price for sequential superposition. Most experienced futures investors suggest dividing the funds into several parts, from more to less, or opening positions in batches in an inverted pyramid. After buying the first part, if the price breaks through the next resistance level, you can continue to buy until you complete the goal of opening a position. In the process of opening a position, the stop loss point is constantly pushed up. For example, after buying the second part, the purchase price becomes the stop loss point. Even if the stop loss is made at this price, the first part of the position is still profitable.
