A backtest or back-test is a hypothetical simulation of an investment or trading strategy. Most backtesting is applied to timing entry and exit points for a particular asset.

Backtesting is one of those things that can be easy to quick and hard to do right.

Portfolio Thinktank uses a Portfolio Backtesting engine that combines recursive optimization and analytics to test portfolio strategy.

This is different than the single asset backtests used by traders. The Portfolio Backtesting at Portfolio ThinkTank is designed to test and refine your compete approach to investing. Investors without any technical experience or coding background can backtest a strategy at Portfolio Thinktank.com for free.
