Review and run

Check your strategy summary below. Review strategy confirms the exact rules before a backtest runs.

Dates and trading costs

Blank dates use all available history. Indicators warm up on earlier bars. Costs apply to entries and exits. Choose dates and costs here, rather than in the strategy text.

Supported rules and examples

Daily single-stock long or short; EMA, SMA and Wilder RSI (2–250 sessions), MACD (12/26/9), close, volume, average volume, thresholds and crossings. Up to six AND or OR conditions per entry/exit group. Fixed targets/stops, close-based trailing stops, maximum holding sessions, dates and costs.

No options, multi-stock portfolios, intraday, weekly/monthly signals, leverage, news/fundamental rules, pyramiding, or nested combinations of AND and OR. Instructions outside these rules will need clarification.

Choose indicators and comparisons in the builder. Operators: above, below, crosses above, crosses below. Indicators: EMA(n), SMA(n), RSI(n), MACD, MACD_SIGNAL, VOLUME_SMA(n). Example: Buy AAPL when SMA(20) crosses above SMA(50) AND volume above VOLUME_SMA(20). Exit when close crosses below SMA(50). Stop 3%.

Before you start

What can I backtest?

The builder supports one stock at a time using daily bars, long or short positions, and supported rules based on EMA, SMA, RSI, MACD, price, and volume. You can add targets, stops, trailing stops, holding limits, dates, fees, and slippage. It does not reproduce options, intraday execution, multi-stock portfolios, or news-based rules.

What historical data does the tester use?

The tester uses daily stock price files supplied to CandleChasers. Choose a symbol to see its available dates and daily sessions. Coverage varies by stock. Each report states its testing period and assumptions.

Are these results real trades or predictions?

Backtests and games use historical data and hypothetical calculations. They are not live trading results or predictions. Daily bars limit execution detail, costs depend on your inputs, and past results do not establish future performance.

Can I change the starting capital and trading costs?

Yes. Set starting capital in the first builder step. Dates, fees, and slippage can be adjusted before you review and confirm the test.

Do I need an account to play the games?

No. Game XP, streaks, and completed rounds are saved in your browser on this device. Clearing browser storage can remove your record, and progress does not automatically sync between devices.

Where should I begin?

Try an editable starter strategy above, find a beginner guide in Trading Education, or play a chart game. You can inspect saved backtests and use calculators to explore the numbers behind a scenario.

CandleChasers provides educational tools and research examples. Hypothetical results are not personalized investment advice.
