# Crypto data and execution
Crypto inverts several assumptions baked into equity tooling: there is **no session, no holiday
calendar, no consolidated tape, no corporate actions — and a far worse survivorship problem.**
## 1. Pick a tool
| Task | Use | Note |
|---|---|---|
| **Connectivity to any venue** | **`ccxt` 4.5.77** (MIT, 43,850★, ~daily releases) | 100+ venues. **Not a backtester — no simulation layer at all** |
| Live L2/L3 feeds | `cryptofeed` 2.5.0 | 🚨 **Python ≥3.12 and no Windows wheel** (sdist only) |
| Binance-specific | `python-binance` 1.0.37 | MIT |
| **Retail bot, live-first** | **`freqtrade` 2026.8** (GPL-3.0, 53,985★) | 🥇 **best bias-detection tooling in the whole field** — see §4 |
| Backtest + live, MIT | `jesse` 3.1.0 (MIT, 8,413★) | Very active |
| Market making / CEX-DEX | `hummingbot` (Apache-2.0, 19,781★) | 🚨 **no Windows wheel**, py≥3.10.12 |
| GUI-first bot | `OctoBot` | GPL-3.0 |
| Serious event-driven, multi-venue | `nautilus_trader` | LGPL-3.0, **needs Python ≥3.12** |
✅ **CCXT Pro is free.** It was merged into the MIT `ccxt` package at v1.95 (2022) — WebSocket
methods (`watchTicker`, `watchOrderBook`, `watchTrades`, `watchOrders`…) are **no longer a paid
product**. Ignore any subscription-expiry notice or tutorial telling you to buy it. Today:
`ccxt` (sync REST) · `ccxt.async_support` · `ccxt.pro` (async + WS) — one package.
Since v4.5.66 it also covers **prediction markets** (Polymarket, Kalshi, Hyperliquid) through the
same unified A
