Tiger API

🯩 What is Tiger API

Tiger API is a local WebSocket server embedded in the Tiger.com Windows terminal that allows external systems (e.g., screeners) to control the interface of the terminal.

🔗 Main Purpose

The setLinkSymbol command instantly opens the specified symbol (e.g., BTCUSDT) in the specified link group (e.g., A) inside the terminal.

⚙️ How to Enable Tiger API in the Terminal

1. Go to: Settings → Local Signal Server

2. Enable the option: Enable Signal Server

3. Press Save

4. Default WebSocket port: 7819

📡 WebSocket Request Format

{
  "type": "setLinkSymbol",
  "e": "BINANCE",         // Exchange
  "m": "SPOT",            // Market type: SPOT or FUTURES
  "symbol": "BTCUSDT",    // Trading pair
  "linkGroup": "A"        // Link group: A–11
}

• All fields are required

📌 Recommendations for Clients

• Always validate JSON locally before sending

• On parsing errors → reconnect using exponential backoff

• Send regular ping messages to keep the connection alive
