Overview

Static JSON data files containing daily OHLCV price data for 10 major cryptocurrencies, used as local data sources for crypto market backtesting.

Description

The crypto daily price data files store historical daily price information for individual digital currencies. Each file follows the Alpha Vantage digital currency JSON schema with a Meta Data header and a Time Series (Daily) object keyed by date. The 10 coins covered are: BTC, ETH, XRP, SOL, ADA, AVAX, DOT, LINK, LTC, and SUI.

Usage

These files are consumed by the local price lookup tool (tool_get_price_local.py) during agent backtesting runs on the crypto market. They are produced by the crypto data fetching pipeline (get_daily_price_crypto.py) and stored under data/crypto/coin/.
