Project description:
"I need a lightweight Windows desktop application that connects directly to the Delta Exchange API and streams tick-by-tick market data for every Indian options and futures contract I select. The feed must update in real time and render clean, responsive charts inside the app without noticeable latency.

Core objectives
• Establish a stable, authenticated connection to Delta Exchange.
• Subscribe to chosen symbols and push each tick straight to the charting layer.
• Allow me to switch contracts on the fly from an easy symbol picker.
• Handle API disconnects or throttling gracefully and reconnect automatically.

Deliverables
1. Compiled Windows installer plus full source code.
2. Brief setup guide showing how to configure keys, select instruments, and start the feed.
3. A quick video or screenshots proving real-time updates under live market conditions.

If the architecture is modular enough to bolt on historical look-ups or alert logic later, that is a bonus, but the immediate requirement is only the live tick stream and chart display. Please build with whatever tech stack you find most efficient—just keep the final executable light, stable, and ready for production use." (client-provided description)
