Data requirements 

• In what format should the data be stored?
• What if I store data in a file with a different extension (not CSV)?
• Can only trading data be integrated?
• What is EOD data? How does it differ from intraday data?
• How quickly can I check the result after updating the data?
• How often do I need to update data from the source?
• What are the limits on the amount of data?
