Frequently Asked Questions

What is OHLC data in crypto?

OHLC data stands for Open, High, Low, and Close, which are key price points for a cryptocurrency over a specific time period.

Open: The price of the crypto at the start of the time period.
High: The highest price reached during the time period.
Low: The lowest price during the time period.
Close: The price at the end of the time period.

With CoinGecko’s API, you can easily access OHLC and OHLCV (OHLC with Volume) data for millions of cryptocurrencies. Our endpoints provide precise, up-to-date, and historical OHLC data, enabling you to:

Build real-time candlestick charts for your trading app or dashboard.
Develop and backtest your trading strategies.
Analyze price movements across different timeframes (e.g., hourly, daily).

Learn more about the OHLC endpoints in our API documentation.

How do I plot candlestick charts using OHLC data with TradingView?

Candlestick charts are powerful visualization tools for displaying price movements over time. By leveraging CoinGecko’s reliable OHLC data and TradingView’s charting tools, you can create visually appealing and insightful candlestick charts for your app or website. Here’s a guide to plot candlestick charts on TradingView:

Get OHLC Data from CoinGecko’s API Use the CoinGecko OHLC endpoint to fetch cryptocurrency OHLC data. Specify the coin, currency, and timeframe (e.g., daily or hourly). CoinGecko’s API delivers the data in a simple JSON format, ready for integration.
Format the Data for TradingView TradingView’s Charting Library requires an array of data points formatted accordingly. Convert the data from CoinGecko’s API to match the structure.
Initialize the TradingView Charting Library Embed the TradingView library into your application. Configure the chart by specifying the symbol, interval, and the data feed that will provide the OHLC data.
Integrate Your OHLC Data Feed Link the formatted data to TradingView’s charting library using its API. The library will render a dynamic candlestick chart, visualizing the OHLC data for the selected cryptocurrency.

For more details, check out our guide to build a candlestick chart application.

How can I create OHLCV candlestick chart with Python?

To create an interactive OHLCV candlestick crypto price chart using Python, you’d need to:

1. Prepare Your Python Environment Ensure you have Pandas, Matplotlib, and mplfinance set up, and have generated your CoinGecko API key.
2. Fetch OHLCV Data with CoinGecko’s API Get the historical OHLCV data using the onchain endpoint: /onchain/networks/{network}/pools/{pool_address}/ohlcv/{timeframe} Use Python to fetch the OHLCV data from CoinGecko API, and structure it into Pandas dataframe for easy handling.
3. Create the OHLCV chart with mplfinance library Use mplfinance to visualize the data collected in Pandas.
4. Chained API calls to fetch network & trading pairs data Fetch detailed token data from both the blockchain network (e.g., Ethereum, Solana) and its trading pairs (e.g., PEPE/USDT). This allows you to dynamically update the chart or app based on the selected network or pair.
