Hi everyone,
I**’**m looking for a reliable and affordable data provider that gives complete trade-by-trade (tick) data for NYSE and NASDAQ stocks, specifically:
• Trade price
• Trade size **(**volume per trade**)**
• Trade direction **(**buy or sell**)**
I**’ve tried Alpha Vantage free tier — it works decently but doesn’**t provide all trades, and the paid plans seem expensive without a clear guarantee of full tick coverage.
My questions:
1. Does Alpha Vantage paid actually give every single trade?
2. What are the best alternatives? I**’**ve heard of Polygon.io, Alpaca, IEX Cloud, Databento, Tradier — any real experience with these?
3. Is trade direction **(**aggressor side**)** actually available from any affordable provider, or do most people infer it using the Lee-Ready algorithm?
4. What**’**s the most cost-effective option for a retail algo trader?
Any real-world experience is appreciated. Thanks!
