Apr 24, 2023 · by CryptoDataDownload

Basic Overview

Gemini is a popular cryptocurrency exchange that provides OHLVC (Open, High, Low, Volume, Close) market data via their API for a wide range of digital assets. This data is essential for traders and investors who want to analyze price trends and make informed decisions about buying and selling cryptocurrencies. Gemini's OHLVC data includes information on historical prices, trading volumes, and other market metrics, which can be accessed through their API or through third-party services that use their data. The accuracy and reliability of Gemini's OHLVC data make it a valuable resource for price analysis.

Code

The code sample will demonstrate how to access the Gemini API in less than 25 lines of Python code; retrieve Open, High, Low, Close and volume information for any pair on Gemini, add a human-readable date column, then save the results to a CSV file. It also allows you to toggle to different timeframes to use. (change the "timeframe" variable in line 24). Timeframes available are: 1 minute (1m), 5 minute (5m), 15 minute (15m), 30 minute (30m), one hour (1hr), six hour (6hr), and finally, daily (1day). Every line is commented for your benefit. Feel free to modify to fit your purpose
