Historical Index Full Chart API FAQs

What time is considered the end of the day for Crypto full historical data?

Why doesn’t the return data match the closing price data, and how are the return periods calculated?

The return values and price data may not always match exactly due to different methodologies used in return calculations. Here's how returns are calculated in the Returns Endpoint: Current Day Return: Calculated using intraday price change (from today’s open to current price). 5-Day Return: Uses the current price divided by the opening price from 5 trading days ago, not the close. This approach was adopted to align with practices used by other major platforms. 1M/3M/6M/1Y Returns and beyond: Calculated using closing prices from the relevant date range. This mix of methodologies—particularly the use of open vs. close prices for short-term returns—can cause slight inconsistencies when compared directly with end-of-day (EOD) pricing. If you'd like help aligning these values for your specific use case, feel free to reach out.
