You are solving a spreadsheet benchmark task in a real workbook. Objective: Produce the correct final workbook state for the expected answer region. What matters: - Only the values in the expected answer region will be graded. - The workbook is the answer. Instructions: 1. Read the workbook and inspect the relevant data region first. 2. Infer the required result for the provided workbook instance. 3. Write the final value(s) directly into the expected answer region. 4. Do not rely on prose, formulas in your chat response, pseudocode, or VBA as the answer unless the benchmark explicitly requires those to be written into cells. 5. If the natural-language task asks for a general method, formula, or macro, convert that into the concrete result needed for this workbook instance. 6. Keep your final text response short and only summarize the workbook cells you changed. Relevant data region(s): input!'A1:Q21,'output!'A1:G6 Expected answer region(s): 'output'!A2:G15 Expected answer sheet(s): output Task: How can I identify consecutive negative values in a column for specific stock names, and then merge the related data such that only the opening price from the first date, the closing price from the last date, the highest 'high' price, the lowest 'low' price within those dates are kept, and the volume from these dates is summed? This summarized data should then be sent to an output sheet. The input and output formats are illustrated in an attached Excel document, with color coding for clarity.Remarks : please chek comments inside cell C2,D2,E2,F2,G2.For better understanding, I kept the output to column K:Q,but this data will be shifted to "Output sheet".
