Use Cases

Monitor overall market sentiment by tracking the biggest losers:
response = requests.get("/api/v1/market/losers")
losers = response.json()["losers"]

# Calculate average decline
avg_decline = sum(stock["changesPercentage"] for stock in losers) / len(losers)
print(f"Average decline among top losers: {avg_decline:.2f}%")
Identify potential buying opportunities in oversold stocks:
def find_oversold_opportunities(losers, min_volume=1000000):
    opportunities = []
    for stock in losers:
        if (stock["changesPercentage"] < -10 and 
            stock["volume"] > min_volume and
            stock["marketCap"] > 1000000000):  # Large cap only
            opportunities.append(stock)
    return opportunities
Monitor portfolio holdings for significant declines:
portfolio = ["AAPL", "MSFT", "GOOGL"]
losers_symbols = [stock["symbol"] for stock in losers]

portfolio_losers = [symbol for symbol in portfolio if symbol in losers_symbols]
if portfolio_losers:
    print(f"Portfolio holdings in today's losers: {portfolio_losers}")
