[ ABOUT ]

Fetches OHLCV candle data from the CoinGecko public API v3 for any coin by its CoinGecko ID (e.g. `bitcoin`, `ethereum`, `solana`). The response contains [timestamp, open, high, low, close] arrays which the function unpacks into a clean dictionary keyed by OHLCV field name.

The CoinGecko free API allows up to 365 days of daily OHLCV data without authentication. Rate limits apply — if scanning more than 50 coins in rapid succession, add a `time.sleep(1)` between calls or use the paid API tier with higher rate limits. The candle data matches TradingView's daily bars when using the same exchange as the data source.

[ USAGE EXAMPLE ]

example.py

data = fetch_ohlcv("bitcoin", days=365)
close = data["close"]   # list of 365 daily closing prices
rsi   = calc_rsi(close)
