Tips

Lookup Sector Name and Code

// Get sector list first to build name-to-code mapping
const boards = await sdk.getConceptList();
const boardMap = new Map(boards.map(b => [b.name, b.code]));

// Find code for a specific sector
const code = boardMap.get('人工智能');  // BK0800

Track Hot Concept Sectors

// Get top 10 concept sectors by change percent
const boards = await sdk.getConceptList();
const hotBoards = boards.slice(0, 10);

// Get leader stock for each hot sector
for (const board of hotBoards) {
  const stocks = await sdk.getConceptConstituents(board.code);
  console.log(`${board.name} Leader: ${stocks[0]?.name}`);
}
