ccxt is a skill for Claude Code, Codex from HKUDS/Vibe-Trading. It costs 27 tokens per session (620 once invoked), scanned A, original, MIT.

A common programming interface for cryptocurrency exchanges, including Binance, Bybit, OKX, Coinbase, and Kraken. It provides public market data such as candles, latest quotes, order books, and recent trades, usually without an API key.

In plain words
What is it for?
Use it to fetch historical OHLCV candles, tickers, order books, and trades for crypto markets. It supports more than 100 exchanges and multiple time periods, from minutes to days.
Why use it?
It lets code request similar data from many exchanges without learning each exchange's separate interface. It can serve as a fallback source when OKX is unavailable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ccxt scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Overview

CCXT is a unified cryptocurrency exchange trading library supporting 100+ exchanges including Binance, Bybit, OKX, Coinbase, Kraken, and more. Public market data (OHLCV, tickers, order books) requires no API key.

Quick Start

import ccxt

exchange = ccxt.binance({"enableRateLimit": True})

# Fetch daily OHLCV
ohlcv = exchange.fetch_ohlcv("BTC/USDT", "1d", limit=100)
# Returns: [[timestamp, open, high, low, close, volume], ...]

# Fetch ticker
ticker = exchange.fetch_ticker("ETH/USDT")
print(f"ETH price: {ticker['last']}")

Key Methods

Method Description Returns
fetch_ohlcv(symbol, timeframe, since, limit) Historical candles [[ts, o, h, l, c, v], ...]
fetch_ticker(symbol) Latest quote {last, bid, ask, volume, ...}
fetch_tickers(symbols) Batch quotes {symbol: ticker}
fetch_order_book(symbol, limit) Order book {bids, asks, timestamp}
fetch_trades(symbol, since, limit) Recent trades [{price, amount, side, timestamp}, ...]

Timeframes

1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 6h, 12h, 1d, 1w, 1M

Note: not all exchanges support all timeframes. Use exchange.timeframes to check.

Symbol Format

CCXT uses slash format: BTC/USDT, ETH/BTC, SOL/USDT

The project's DataLoader automatically converts BTC-USDT (hyphen) to BTC/USDT (slash).

Exchange Selection

Set via environment variable: CCXT_EXCHANGE=binance (default)

Popular exchanges: binance, bybit, okx, coinbase, kraken, bitget, gate

Built-in Loader

The project has a built-in CCXT DataLoader at backtest/loaders/ccxt_loader.py. It serves as a fallback when the OKX loader is unavailable.

Pagination

For long history, CCXT paginates via the since parameter (millisecond timestamp). The built-in loader handles this automatically (up to 200 pages).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
