The order book, recorded. And the AI built on it.
L2WS records the full Binance order book and trade tape over WebSocket, verifies every day, and turns that record into three products: the market data itself, AI price levels, and the decisions of our own trading model.
Market data
The full-depth order book and complete trade tape, the way the exchange streamed it.
- Order-book diffs at 100 ms, 5-minute snapshots
- Every trade, checked daily against the exchange archive
- SQL console, backtests, REST API and MCP
AI price levels
Support and resistance from several AI models — with every past level and what price did next.
- BTC, ETH and SOL, refreshed through the day
- Full history with observed outcomes
- Web, API, MCP and TradingView export · from $0.99
AI trader
The decisions of our own trading model: enter, exit or wait. You get decisions, never the model.
- 1,153 GPU hours of training so far
- 76 exams on held-out 2026 weeks, fees included

The archive's schema, in real time. Join the list →
Four layers, written as the exchange streams them.
Every message from Binance's WebSocket lands in one of four layers, keeps its local receive time, and is checked again the next day against the exchange's own archive. Gaps are marked, never filled in.
- 41 streams across spot and USD-M futures
- 0 missing trades against the exchange archive on 2026-11-14
- Daily quality index 100 and a full order-book replay check
One record, four ways in
The data stays with us; the results go to you. No downloads to manage, no egress bills.
