Summary
- Post is a question about sourcing low-cost Level 2 ticker data for algorithmic trading experiments.
- Author notes most streaming L2 services exceed $1k/month, too expensive for a small-scale trial.
- No specific trading strategy, asset class, or directional thesis is presented; this is an infrastructure/data sourcing inquiry.
Quality assessment: Noise / informational inquiry — not investment research, no backtested data, no tradeable thesis.
