问财查询当天的实时资金流向为0

The screenshot you provided seems to indicate that the query for real-time money flow data returned zero results. This means there is currently no available information on the actual funds being flowed in or out of any security as per your specified criteria.

However, if I were to provide an explanation based on my previous knowledge:

When using functions like get_money_flow_step with parameters including a list of securities, date range, and frequency step (in this case daily), aiming to fetch data related to 'actual' buy quantities (act_buy_xl, act_buy_l, act_buy_m) etc., an output of zero typically indicates that no transactions meeting the criteria have occurred during the specified period or across listed securities. This could be due to various reasons:

1. Lack of Market Activity: There might not have been any significant trading activity involving the securities you're tracking.
2. Data Availability Issues: The API might not have access to real-time data for all requested securities, especially if they are less liquid or not frequently traded.
3. Specific Criteria Not Met: It's possible that the defined frequency step (1d) and/or date range ('2023-04-05'-'2023/05/06') doesn't overlap with any trading periods during which funds flowed as per your specific fields.

For more accurate insight, it would be beneficial to check the following:

1. Update API Call: Ensure that you're using the most recent version of the function and API data feeds.
2. Date Ranges: Confirm if there's a recent enough period specified for your query (e.g., adjusting end_date from 'now' might help since now returns real-time data).
3. Security List: Verify that all securities in your list are active and have trading data available.

If you need further assistance with specific functions or queries, please provide more details or ask direct questions regarding the process or parameters involved.
