📈 Ethereum Candlestick Chart Generator

This project fetches Ethereum (ETH) price data for the past 30 days from the CoinGecko API and visualizes it as an interactive Candlestick Chart using Plotly. The chart is saved as an HTML file and automatically opened in your default web browser.

🚀 How It Works

This project performs three main steps to generate a candlestick chart for Ethereum using live market data:

1. Fetch Ethereum Data

The script pulls ETH market data from CoinGecko's API for the last 30 days using the get_eth_market_chart() function.

eth_data = get_eth_market_chart()

2. Convert to OHLC Format

The raw price data is resampled into daily OHLC (Open, High, Low, Close) format using Pandas' .resample() method.

ohlc = convert_to_ohlc(eth_data)

3. Plot Candlestick Chart

An interactive chart is created using Plotly and opened in your default browser:

plot_candlestick_to_browser(ohlc)

📌 Customization Tips

• Change Currency: Modify the vs_currency='usd' parameter in get_eth_market_chart() to another currency like eur, inr, gbp, etc.

• Adjust Time Range: Modify the days parameter to '7', '90', '365', or 'max' to change the time window of the data.

• Dynamic File Naming: To avoid overwriting charts and save with the current date:

  filename = f"eth_candlestick_{datetime.now().strftime('%Y-%m-%d')}.html"
