Steps to run this example:
1. Import data/TWAPDATA.csv into the dolphindb/server directory, i.e., the server directory under the DolphinDB service installation path.
2. Import data/dashboard.DC_TWAP_Monitoring.json into the dashboard.
3. Run data/data_input.dos to create databases and tables, and import data into the tables.
5. Run scripts 01 through 07 in sequence to build the TWAP order slicing system.
6. Run script 08 or Java/Python API code to place parent orders into the subscription stream table
7. Observe the dashboard results; the parent order monitoring shows the placed parent orders;
In the child order monitoring, it will show the buy orders placed by the slicing system;
The change order monitoring records the management notifications issued for parent orders.
