Tips

Lookup Sector Name and Code

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

// Find code for a specific sector
const code = boardMap.get('互联网服务');  // BK0447

Find Sector Leader

// Get constituents (already sorted by change percent)
const stocks = await sdk.getIndustryConstituents('互联网服务');

// The leader is the top stock
const leader = stocks[0];
console.log(`Leader: ${leader.name} Change: ${leader.changePercent}%`);
