Where do the data used by Lucy come from?

At Lucy, every analysis is based on a fundamental principle: No good decision without reliable data. That's why we've designed a robust infrastructure that retrieves, centralizes, and processes in real-time the most relevant crypto market data — with rigor, precision, and transparency.

Reliable data sources

Data from the most reliable market sources

We connect directly to APIs recognized for their reliability, speed, and market coverage.

🏦 Exchange platforms (CEX)

For spot price data, volumes, open interest, volatility:

  • Binance
  • Coinbase
  • Kraken
  • Bybit
  • Bitfinex
  • OKX
  • KuCoin

These sources allow us to obtain a direct and raw view of the order book and the real market dynamics.

Aggregation platforms

Aggregation & analysis platforms

For market cap, temporal variations, sector dominance, blockchains, categories, etc.:

  • CoinMarketCap
  • CoinGecko
  • Messari
  • CryptoCompare

These aggregators structure cross-referenced data, which we clean and validate before injecting into our analysis engine.

Real-time data updates

An update every 10 minutes

Data is never static. That's why our system is configured to perform a complete refresh every 10 minutes across all tracked cryptos.

This allows you to:

  • Reduce latency in signals
  • Track micro-variations across multiple timeframes
  • Provide results in phase with the present moment

No data comes from long-term cache. Everything is dynamically reloaded with each user request.

Processing engines

Ultra-high-performance internal processing engines

Raw data is then processed by two proprietary engines:

Harvesting engine

  • Aggregates all available data
  • Formats it into exploitable objects
  • Applies validation protocols to detect inconsistencies or duplicates

Analysis engine

  • Calculates technical indicators on the fly (RSI, MACD, MA, etc.)
  • Detects support/resistance by recurrence + bounces
  • Identifies candlestick patterns across multiple timeframes
  • Interprets trends via histograms, variations, and market structure

Everything works with reduced error tolerance and an integrated anomaly detection system.

Trusted results

Why you can trust the results

We don't base any analysis on fuzzy estimates or secondary data. Every asset you see in our results has been:

Every asset you see in our results has been:

  • Cross-referenced across multiple sources
  • Recalculated locally for validation
  • Contextualized (blockchain, category, sector, liquidity, etc.)

If a crypto appears in a result, it's because it truly met the conditions in real-time.

Future infrastructure

And this is just the beginning

Lucy is built on real-time data infrastructure, designed for speed, accuracy, and robustness.

This means that:

  • You don't depend on "data from yesterday"
  • You get a real snapshot of the market at time T
  • You can make decisions with a reliable, clear, and structured foundation
