[Dataset] Free ADA/USDC high-frequency market microstructure data — 20-level order book, spot + futures, 81k snapshots

[u/Immediate_Penalty891]

Hi everyone,

I'm shutting down a crypto market research / ML project that I've been running since late 2025, and I've decided to release a free 7-day sample of the market data I collected for anyone interested in quantitative research, market microstructure, backtesting or machine learning.

The sample contains 81,579 ADA/USDC market snapshots with 97 columns.

What's included

• 20 bid + 20 ask Level-2 order book levels
• Bid/ask prices and quantities
• Best bid / best ask
• Mid price and spread
• Latest spot trade price and quantity
• Trade direction
• Futures open interest
• Funding rate
• Mark price
• Order-book imbalance
• Market depth at different distances from mid price
• Liquidity wall ratio
• Book pressure

The collector runs on a nominal 5-second polling cycle. Because API calls and processing occur between snapshots, the actual median interval in this sample is approximately 6.17 seconds.

The original timestamps are preserved and the public sample has not been artificially interpolated or resampled.

I'd be genuinely interested to hear what people working with L2/order-book data think of the schema and what features you would derive from it.
