Market Data API Showdown: AllTick vs Bloomberg vs Alpha Vantage

A technical comparison of three market data APIs—AllTick, Bloomberg, and Alpha Vantage—evaluates granularity, latency, and integration complexity. AllTick offers 100 req/min free tier with tick data and WebSocket streaming, while Alpha Vantage is limited to 5 req/min and no real-time. Bloomberg provides sub-10ms latency but requires enterprise contracts.
