Quantitative Factors and Construction Methods - **Factor Name**: Large Order Transaction Amount Ratio **Factor Construction Idea**: This factor captures the buying behavior of large capital by analyzing the proportion of large order transaction amounts in the total daily transaction amount[8] **Factor Construction Process**: 1. Use tick-by-tick transaction data to identify buy and sell orders based on the sequence numbers of bids and asks 2. Filter transactions by order size to identify large orders 3. Calculate the proportion of large buy order transaction amounts in the total daily transaction amount **Formula**: $ \text{Large Order Transaction Amount Ratio} = \frac{\text{Large Buy Order Transaction Amount}}{\text{Total Daily Transaction Amount}} $ **Evaluation**: This factor effectively reflects the buying behavior of large capital[8] - **Factor Name**: Net Active Buy Transaction Amount Ratio **Factor Construction Idea**: This factor measures the active buying behavior of investors by calculating the net active buy transaction amount as a proportion of the total daily transaction amount[8] **Factor Construction Process**: 1. Use tick-by-tick transaction data to classify each transaction as either active buy or active sell based on the buy/sell indicator 2. Subtract the active sell transaction amount from the active buy transaction amount to obtain the net active buy transaction amount 3. Calculate the proportion of the net active buy transaction amount in the total daily transaction amount **Formula**: $ \text{Net Active Buy Transaction Amount Ratio} = \frac{\text{Active Buy Transaction Amount} - \text{Active Sell Transaction Amount}}{\text{Total Daily Transaction Amount}} $ **Evaluation**: This factor provides insights into the active buying tendencies of investors[8] --- Factor Backtesting Results - **Large Order Transaction Amount Ratio**: - Top 10 stocks with the highest 5-day average values: 1.
