Backtest

UPDATED 2026-08-01

A backtest is a historical simulation that replays a strategy's rules over past market data to show what it would have done. It applies the strategy's own allocation, rebalancing, and exit rules step by step across history and produces an equity curve plus performance metrics. In Fincanva, "backtest" means this historical simulation for every strategy type — there is no separate "backtest" kind of strategy.

What does a backtest measure?

A backtest measures what a strategy's own rules would have produced over historical market data, reported as an equity curve plus the metrics that summarise it — CAGR, Max drawdown, Sharpe ratio and the rest of the metrics view.

It measures the whole path, not only the end point: two strategies can finish at the same value having taken very different routes there, and the curve is what shows the difference. What it does not measure is anything outside the rules you saved — it makes no judgement about whether a strategy is suitable for you, and it says nothing about periods the chosen instruments have no data for. See How backtesting works for the step-by-step mechanics.

Defaults in Fincanva

  • A backtest runs from the earliest year your chosen instruments and plan allow, through the latest available market close; its end date follows the newest data, not today's calendar date.
  • Results are cached and refresh daily as new market data arrives, so the same strategy's numbers can shift from one day to the next with no change to its settings.
  • Identical strategies share one computed result, so a backtest may already be running because someone else requested the same configuration.
  • Saving and running is the reliable way to (re)compute today — it applies your latest settings and starts a fresh run.

Worked example

A two-asset strategy holds 60% in a stock ETP and 40% in a bond ETP, rebalancing back to 60/40 twice a year. The backtest starts both sleeves from the same capital and replays every trading day; at each rebalance date it trims whichever sleeve has grown past its target and tops the other back up to weight. After two rebalances, the equity curve reflects both the market's moves and the two corrections back to 60/40, and the metrics summarise that whole path. See how a backtest works for the step-by-step mechanics.

A backtest describes what a strategy's rules would have done on historical data, not what they will do, and past results are never a promise of future ones. Fincanva provides no financial advice — see Is this financial advice?.
