The short - term model focuses on market style, external factors, and capital market high - frequency financial data, while the long - term model focuses on market expectations and low - frequency macro - economic data. The position volume is synthesized based on institutional long and short positions [17]. - The comprehensive signal strength is weighted by the signals of three independent models (0 - 1). Contracts with the top two comprehensive signal strengths greater than or equal to 0.6 are considered for long positions, and those with the bottom two less than or equal to 0.4 are considered for short positions. Position volume signals are shielded 7 days before contract expiration. An intraday decline of more than 1% is set as the stop - loss point, and funds are equally weighted. Signals in the same direction for two consecutive trading days are shielded [18][19]. 3.3 Last Week's Situation - From May 19 to May 23, the positions of IF, IH, IC, and IM were all 0, while the position of T was 1 on May 19 and 20 and 0 for the rest of the days, and the position of TF was 0 throughout the week [20]. 3.4 Recent Income Performance - The previous day's return was 0%, the return for the past week was 0.45%, the return for the past month was 0.78%, the return for the past three months was 1.45%, the return for the past six months was 5.26%, the return for the past year was 8.51%, and the return for the past three years was 23.99%. The maximum drawdown for the past week was 0%, for the past month was 0.05%, for the past three months was 0.07%, for the past six months was 0.52%, for the past year was 0.59%, and for the past three years was 3.27% [22]. 3.5 Treasury Bond Futures Cross - Variety Arbitrage Strategy - The cross - variety arbitrage strategy is based on the signal resonance of the fundamental three - factor model and the trend regression model. The fundamental factor uses the instantaneous forward - rate function proposed by Nelson and Siegel, which decomposes the interest - rate term structure into level, slope, and curvature. The signals are divided into three types: '1' (large spread may decrease), '0' (uncertain spread trend or oscillation), and '-1' (large spread may increase). The trend regression model is used to filter signals, and trading occurs when there is resonance. In actual operation, the 10 - 5Y spread is adjusted with a duration - neutral ratio of 1:1.8 [23]. - For the TF and T main contracts from May 19 to May 23, the N - S model and trend regression model signals mostly showed '0', except that the N - S model signal was '1' on May 21 and 22 [26].
