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.
For that calculator, we acquired the data using the Twelve Data API (i don't have link; my friend got the data), which only allowed 800 requests per day on the free version, meaning we weren't able to get very much out of it (~14000 datapoints). We recently switched over to a new, 120,000 datapoint dataset we generated using a python library called yahooquery, which gives us unlimited requests. DM me for more info, if you want.
