To get closer to the target, we need to buy more shares.\n- The current cash is 0.0474, and the loan capacity is 2.9813. To keep the risk moderate, we should not borrow too much. In this case, we are not borrowing.\n- The current price is 4.5938, and the own valuation is 4.6349. To keep the risk moderate, we should not pay too much for the shares. In this case, we set a limit price of 4.6.\n- The quantity to buy is calculated as (target_holdings - current_holdings) / (current_price / limit_price). In this case, it is (11.7134 - 1.298) / (4.6349 / ", "usage": {"prompt_tokens": 361, "completion_tokens": 300, "total_tokens": 661, "prompt_tokens_details": {"cached_tokens": 167}}, "fingerprint": "0.31.3-0.31.2-macOS-26.4-arm64-arm-64bit-Mach-O-applegpu_g15d", "attempts": 1, "error": ""}
