Quantitative Models and Construction Methods 1. Model Name: Large Order Transaction Amount Ratio - **Model Construction Idea**: This model tracks the buying behavior of large funds by calculating the proportion of large order transaction amounts to the total daily transaction amount[7] - **Model Construction Process**: 1. Use tick-by-tick transaction data to identify buy and sell orders based on bid and ask sequence numbers 2. Filter transactions by order size to identify large orders 3. Calculate the ratio of large buy order transaction amounts to the total daily transaction amount - Formula: $ \text{Large Order Transaction Amount Ratio} = \frac{\text{Large Buy Order Transaction Amount}}{\text{Total Daily Transaction Amount}} $ - **Model Evaluation**: This indicator effectively captures the buying behavior of large funds[7] 2. Model Name: Net Active Buy Amount Ratio - **Model Construction Idea**: This model measures the active buying behavior of investors by calculating the net active buy amount as a proportion of the total daily transaction amount[7] - **Model Construction Process**: 1.
