High-speed cryptocurrency OHLCV data downloader via concurrent API requests

Intro

• Downloads crypto kline (candlestick) data fast by making as many concurrent API requests as possible
  • Takes 3 minutes to download 1 month of entire market data (597 symbols), with 5 minutes time interval

Usage

pip install crypto-data-downloader

import asyncio

from crypto_data_downloader.binance import ALL_COLUMNS, CryptoDataDownloader
from crypto_data_downloader.utils import load_pkl, plot_crypto_data

# Refer to https://developers.binance.com/docs/binance-spot-api-docs/rest-api/market-data-endpoints#klinecandlestick-data


x = CryptoDataDownloader()
x.weight_lim = 5000  # Binance request weight limit per minute, max: 6000
x.quote = "USDT"  # Quote asset
x.interval = "5m"  # Kline time interval
x.kline_lim = 1000  # Kline number of data points per request
x.columns = ["open_time", "close"]  # Data columns to include
print(f"All data columns: {ALL_COLUMNS}")
asyncio.run(x.download("2025-07-01", "2025-08-01"))  # Time in UTC

path = f"data/{x.name}_2025-07-01_2025-08-01.pkl"
data = load_pkl(path, gz=True)
plot_crypto_data(data, path)

• Output

All data columns: ['open_time', 'open', 'high', 'low', 'close', 'volume', 'close_time', 'quote_volume', 'n_trades', 'taker_buy_base_volume', 'taker_buy_quote_volume', 'unused']
weight lim: 5000/6000, USDT symbols: 597, spot: 557, margin: 401
