Relative Strength Index API FAQs

The RSI value is above 100 for several stocks. Is this expected or a bug?

To ensure accurate RSI calculations, please try extending the date range to be longer than the selected period.

How the "from" and "to" parameters works for the Technical Indicator API?

The from and to parameters will limit the amount of records the RSI (for example) is calculated from. If you only give it one day, it will calculate only on limited records. The period length should be around the same as your query interval.

How are sentiment scores computed for the Stock News Sentiments RSS Feed API?

The sentiment scores for the Stock News Sentiments RSS Feed API are computed based on the number of positive and negative/neutral comments received in a 24-hour period. For example, if there are 500 positive comments and 500 negative/neutral comments, the sentiment score would be calculated as (500 * 1) + (500 * 0) = 500. The average mentions per day value would then be 500 / 1000 = 0.5. Additionally, the Average Hype Index (AHI) and Relative Hype Index (RHI) are calculated to provide further insights into sentiment.
