InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Price-wise, if you want the history, you can pull the entire dataset from IQFeed (https://github.com/nhedlund/qdownload is fast and easy) or Kibot (with their agent) for the ~$100, and then use whatever you want for your ongoing data. It should only take a few hours/days depending in your connection speed, so I'd consider either of those subscriptions as "one off" charges as well.
