📝 Notes

Financial ratios calculations are perfomed on all dates and then filtered by Bollinger bands on basis of window_size,- Allows Storing all financial ratios (if ratios_to_file parameter is set to True)

• More Analysis and calculations can be performed now that all ratios data is saved to a feather file as well
• Final outcome : feather file for ratios and / or bollinger + returning the same for models
• Further down can implement Caching mechanism to manage all records in better manner and make them readily available for Bollinger bands or other calculations
