TAO Detector is a cryptocurrency new-listing detection system that continuously monitors Binance and OKX exchanges and identifies newly listed coins as early as possible. As soon as a new listing appears, the system automatically downloads the first 7 days of 1-minute OHLCV data from the genesis candle for early-pattern analysis.

The pipeline is built around async candle downloaders and per-exchange detection scripts, with structured CSV storage organised for fast downstream analysis. The dataset is designed to support quantitative research on early price movements, volume patterns, and trading-strategy development for newly listed assets.

What I built

Multi-exchange listing detection
Continuous monitoring of Binance and OKX with detection logic that flags new symbols the moment they become available on each exchange.
Async OHLCV backfill
Async candle downloaders pull the first 7 days of 1-minute OHLCV from the genesis candle, with retry logic and storage management for large datasets.
Structured CSV storage
Per-exchange CSV layout with full OHLCV columns plus trade counts and taker base/quote volumes, ready for direct ingestion into Pandas notebooks.
Historical listing database
Maintains a full historical record of detected listings so quants can backtest strategies on early-listing behaviour across multiple coins and exchanges.
