At a glance
Fetches public crypto market data (candles, tickers, order books, trades) from 100+ exchanges through CCXT, and serves as the fallback when OKX is unavailable.
- Downloading historical crypto candles without an API key
- SKILL.md covers Overview, Quick Start, Key Methods and Timeframes, plus 4 more sections
- Calls pip
- Getting a live ticker or order book from an exchange
What it does
CCXT is a unified Python library for cryptocurrency exchanges, covering 100+ of them including Binance, Bybit, OKX, Coinbase and Kraken. The skill sticks to public market data, which needs no API key, and lists the key methods: fetch_ohlcv for historical candles, fetch_ticker and fetch_tickers for quotes, fetch_order_book and fetch_trades.
Practical details include the slash symbol format such as BTC/USDT, which the project's loader converts from the hyphen form, the supported timeframes from 1m to 1M (check exchange.timeframes, since support varies), exchange selection through the CCXT_EXCHANGE variable with binance as the default, and pagination through the since parameter. The built-in loader pages automatically up to 200 pages and acts as a fallback when the OKX loader is not available.
When your agent uses it
- Downloading historical crypto candles without an API key
- Getting a live ticker or order book from an exchange
- Falling back to CCXT when the OKX loader is unavailable
- Choosing symbols and timeframes that an exchange supports
Example prompts
- “Fetch hourly BTC/USDT candles from Binance for the last week.”
- “Show the current order book for ETH/USDT on Kraken.”
- “Switch the data source to Bybit using the exchange variable.”
- “Which timeframes does OKX support in CCXT?”
Requirements
- Python with ccxt (pip install ccxt)
- Network access to the exchanges' public APIs
What it can do on your machine
Read from SKILL.md and the folder at commit 7f6908b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
CCXT Crypto Market Data loads about 544 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 191 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
- GitHub: https://github.com/ccxt/ccxt (35k+ stars)
- Install:
pip install ccxt
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).
