Criteria for Quality Backtesting Data

  • Completeness: It should cover all necessary market events and price points.
  • Frequency: High-frequency data can provide more precise results for some strategies.

Steps to Conduct Lean Backtesting: A Systematic Approach

Conducting lean backtesting requires a structured and meticulous approach. Following a set of steps ensures that the process is efficient and the results, reliable.
