🔥 BONUS MODULE DROPPED: WebSockets for Real-Time Market Data
Just added a new bonus to the 7-Day Trading System course — a full walkthrough on WebSockets and how to stream live order book data from Deribit using async Python.
Here's what's inside:
→ What WebSockets are and why every exchange uses them
→ REST polling vs WebSockets (and why polling is killing your edge)
→ The upgrade handshake — how HTTP becomes ws://
→ Async producer/consumer architecture with asyncio.Queue
→ Full working code: connect to Deribit, subscribe to BTC-PERPETUAL order book, and process updates in real time
→ Production tips: reconnection, heartbeats, persistence, multi-symbol
This is the same pattern used in professional trading infrastructure — one coroutine receives data from the exchange, another processes it independently. Clean separation. Backpressure built in. Swap out the processor for your own strategy logic without touching the receiver.
If you're building anything that touches live market data, this is foundational.
Go check it out inside the course. Drop a 🔥 if you want more content like this.
