What is a stock backtester?

Before you trade a strategy, backtest it. A stock backtester replays a trading rule over a stock's real price history and shows what would have happened: the equity curve, how it compares to simply buying and holding, how many trades it took, the win rate, and the worst drawdown along the way. This one supports the classic strategies — moving-average crossover, RSI, MACD, Bollinger Bands — with tunable parameters and trading fees, all running instantly in your browser on free Yahoo Finance data. It's the research companion to a stock trading bot: prove the idea here, then automate it.

Common features

  • SMA-crossover, RSI, MACD and Bollinger strategies
  • Equity curve vs buy-and-hold
  • Win rate, trade count and max drawdown
  • Tunable parameters and trading fees
  • Any US ticker; free Yahoo Finance data (no key)
  • No look-ahead — signals act at the bar's close

Real-world examples

Crossover on AAPL

Test a 10/30 moving-average crossover on Apple and see whether it beat buy-and-hold after fees.

RSI mean-reversion

Tune RSI oversold/overbought levels on a ticker and inspect the win rate and drawdown.

Strategy shootout

Flip between SMA, RSI, MACD and Bollinger on the same stock to see which held up best.

Why Cryptohopper.AI fits stock backtester projects

Cryptohopper.AI ships the whole backtester — the simulation engine, the metrics and the equity-curve chart — from one description, with no API key to wire. Change the ticker, strategies or fees by chatting; pair it with the stock trading bot to take a proven strategy live.

常见问题

What does the stock backtester do?
It simulates a trading strategy (SMA crossover, RSI, MACD or Bollinger) on a stock's real historical daily prices and reports the equity curve, total return vs buy-and-hold, number of trades, win rate and maximum drawdown — so you can sanity-check an idea before risking money.
Does it need an API key?
No. It pulls daily price history from a free public source (Yahoo Finance) server-side, so it works the moment it's generated — no signup.
Which ticker and strategy can I test?
Any US ticker (set via a project secret, e.g. AAPL, MSFT, BRK.B) and any of the built-in strategies, with the parameters and fees fully tunable in the UI.
Is a good backtest a guarantee?
No — backtests show how a strategy WOULD have done on past data, with no look-ahead, but past performance doesn't guarantee future results. It's a research tool, not financial advice.
