Guided course path

Keep backtesting basics inside the live track.

You are reading a reference lesson. The live course path gives you the lesson order, checks, saved progress, and next step. Execution makes more sense after the chart bias, key levels, and timeframe context are clear.

What Is Backtesting?

Backtesting means applying your trading strategy to historical price data to see how it would have performed. It's like a flight simulator for traders — you practice without risk to build confidence and refine your rules.

Wick saysBacktest by hiding the future and stepping forward one candle at a time.

Manual Backtesting

Scroll back on your chart, cover the right side, and step forward candle by candle. Apply your entry rules. Record each trade as if it were live. You need at least 50-100 trades for statistically meaningful results.

Wick saysTest at least 50 to 100 trades and track the same few numbers every time.

Key Metrics to Track

Track: Win Rate (%), Average Win vs Average Loss, Profit Factor (gross profit ÷ gross loss), Maximum Drawdown, and Total Return. A strategy with 45% win rate and 1:2 RR can still be very profitable.

Wick saysInclude spreads and fees in your backtest, or the results will look better than real life.

Common Backtesting Mistakes

Curve fitting (over-optimizing to past data), ignoring spreads/commissions, testing too few trades, and hindsight bias (seeing what happened next while deciding entries). Be honest and strict with your rules.

Did it stick?

Try to answer each one before you peek at the explanation.

How many trades should you have for a statistically meaningful backtest?

Curve fitting means your strategy is perfectly optimized for live trading.

Match each metric to what it measures:

Win Rate→Percentage of trades that profit
Max Drawdown→Largest peak-to-trough decline
Profit Factor→Gross profit ÷ gross loss
