Did your trades beat doing nothing?

Compare your actual trading performance against a counterfactual "Buy & Hold" baseline from any historical date to today.

The Ideal "Golden" File Combination:

For 100% mathematical precision across multiple years, pairing a December Year-End Statement PDF (as your starting baseline) with your Transaction History CSV and Current Positions CSV gives the most accurate simulation.
