Create a Windows Service to extract currency trade history from 3 exchanges at configured intervals and save the extracted data to an SQL Server database table. The 3 exchanges have APIs that return the trade history in JSON format. The APIs have usage limits so the developer will be required to design the Windows service so that the APIs can be called at configured intervals. The database table schema is already created and has only 6 fields.
We will provide all documentation needed for project, as well as SQL file. We simply need you to create the service, pull the API data, and dump it in the database.
We need this done asap, project is $500 flat rate.
