What is Fundamental Backtesting?
While technical backtesting uses price and indicators, fundamental backtesting evaluates strategies based on business or network metrics like:
Earnings, revenue growth, and valuation ratios (stocks)
On-chain metrics like active addresses or transaction volume (crypto)
Backtesting these inputs helps you understand how buying based on fundamentals would have performed over time.
Example:
Buy crypto projects with consistent wallet growth and active dev activity
Backtest performance over 1–3 years
