Learn to read a backtest, then check it yourself. AvalonQuant re-runs famous investing methods and its own strategies on decades of past data with the same engine and costs, and publishes the method, the out-of-sample results and the limits alongside the numbers. Backtests, virtual trading and real-money records are kept apart. Education and public records only: no stock picks, trading signals or return promises.

Backtest learning path

1. Start: tell the kinds of results apart

Learn what backtests, virtual trading and real-money records each tell you, with the basic terms.

2. Reading metrics: drawdown before return

How CAGR, max drawdown and the Sharpe ratio are calculated and compared, with a calculator to try them.

3. Pitfalls: question a backtest that looks good

Overfitting, look-ahead, survivorship bias and trading costs: the usual ways a backtest gets inflated, and how to check for them.

4. Strategy anatomy: re-run on real data

Read well-known methods and published strategies re-run with the same engine and costs, rules included.

Backtest → Virtual trading → Real money

  1. Backtest — 6 strategies re-run on historical prices
  2. Virtual trading — 5 strategies on live prices with simulated orders; 0 ranked after 28+ days
  3. Real money — Not yet

Warming up and not ranked yet

A strategy joins the ranking after 28 days of virtual trading with at least one fill. Until then it is listed here without performance numbers, so a few days of results do not read as a track record. Strategies whose virtual trading observation is paused are listed here too.

Strategy backtests, lowest drawdown first

Backtest = historical simulation on past prices, not real trading.

All re-run strategy backtests
