What this file is

Demonstration script for server-streaming APIs (real-time subscriptions). Shows how to consume async streams and handle cooperative cancellation.

Low‑level methods used here

• on_symbol_tick(...) → see on_symbol_tick.md
• on_trade(...) → see on_trade.md
• on_opened_orders_tickets(...) → see on_opened_orders_tickets.md
• on_opened_orders_profit(...) → see on_opened_orders_profit.md

Tips for working with stream demos

• Cooperative shutdown. Pass a cancellation event and stop cleanly.
• Back-pressure. Debounce or sample incoming ticks to avoid UI/CPU spikes.
• Scoped subscriptions. Keep symbol lists compact; use snapshots (quote_many) for refills.
• Structured logging. Log symbol, bid/ask, latency markers; avoid per-tick verbose logs.

Output

You should see a rolling log of streamed updates (ticks, trades, tickets, etc.).
