Kamakura Quant Lab

鎌倉クオンツラボ 日本語

Japanese crypto markets, quantitatively

Kamakura Quant Lab does three things, all aimed at Japanese cryptocurrency exchanges.

Quantitative trading
Forming ideas from order book and trade data, testing them, and running them.
Sharing what we learn
Writing up methods and their limits, reproducibly. Including the measurements that turned out to disagree with the idea, which are usually the more useful half.
Building the systems
Collection, storage, verification and backtesting, built in-house. JP Market Archive fell out of that, and is the only part currently for sale.

Market Archive

L2 order book depth and public trades from bitbank, Coincheck, GMO Coin and Binance, stored one partition per Asia/Tokyo day. Most venues publish their own trade history; almost none publish depth, and depth is what microstructure work usually needs. The Japanese venues and Binance share one timeline and one layout, so a lead-lag study starts immediately.
