You need fast and right data for a gold or silver app. Speed helps users make better choices.

Here is how you build the data path:

• Get data from APIs using REST for history and WebSocket for real-time updates.
• Use a gateway to sort different metals.
• Store new prices in Redis.
• Store old data in MySQL.
• Put tick data in a time-series database.

For the charts, use TradingView Lightweight Charts. It is open source and fast. It works great on mobile phones.

To make price alerts work:

• Group alerts by the metal symbol.
• Only check prices for the symbol.
• Send a push note when the price hits the target.

Keep the app fast on phones:

• Reduce the amount of data for long time frames.
• Use Canvas to draw the charts.
• Update only the newest price point.

For a large app, use microservices. Use Kafka to send data between parts. This lets you grow without crashes.

Start with a small version. Focus on the data speed first. Add more tools later.
