Dual Exchange Futures Trading Bot

I need a lightweight web application that connects to two futures exchanges (I’ll confirm which ones—my choice falls under “other” rather than the standard pairs listed). The core tasks are:

• Stream live futures prices from both exchanges in real time.
• Display my current public-IP address somewhere obvious in the UI.
• Let me open and close both LONG and SHORT positions on either exchange with a single click, using their respective REST/WebSocket APIs.

The interface should remain simple and minimalistic—clean price feed, order panel, and IP read-out, nothing more. Authentication will rely on API keys for each exchange; the app must provide secure storage and encrypted transmission of those keys.

I’m open on tech stack, but speed and stability are crucial, so please propose whatever combination of Node.js, Python, Flask, FastAPI, React, or similar you’re most comfortable with. I’ll test the build by:

1. Viewing live bid/ask updates within 200 ms of the exchange feed.
2. Seeing my IP address refresh accurately on page load.
3. Placing a market long and a market short on both exchanges and receiving immediate order-status feedback.

Hand-off deliverables: source code, brief setup guide, and a short demo video or call proving the three points above.
