I’m building my own trading platform and need clear, actionable guidance on getting a valid Quotex trading API key so I can stream real-time data. Here’s what I expect: • Step-by-step instructions for requesting, activating, and securely storing the Quotex API key. • Confirmation that the key supports real-time data streaming—this is the single most critical feature for me. • A concise example (Python preferred) showing how to connect with the key and subscribe to live quotes for the forex pairs I trade most often: EUR/USD, USD/BRL, and AUD/CAD. • Tips on any common pitfalls (rate limits, IP whitelisting, sandbox vs. live mode) so I avoid surprises later. A straightforward, well-documented walkthrough is all I need at this stage; no full trading logic or UI work is required yet.
