1. Use High-Quality, Clean Historical Data

Your backtest is only as good as your data. Bad data = bad results.

✅ Do this:

Use reliable sources like Binance, CoinGecko, CryptoCompare, Yahoo Finance

Remove anomalies and fill missing values

Check timestamps, time zones, and consistency

❌ Avoid:

Using low-resolution data for short-term strategies (e.g., 1D data for scalping)

Mixing datasets without aligning formats

2. Include Realistic Market Conditions

Many traders backtest without considering how the market really behaves.

✅ Do this:

Add slippage, spreads, and trading fees

Simulate partial fills and order execution delays

Adjust for volatility spikes and liquidity drops

❌ Avoid:

Unrealistic “perfect fills” or zero-cost trades

Only testing during bull markets

3. Optimize Parameters Carefully

Optimization improves results—but only when done right.

✅ Do this:

Run grid or random search for inputs (e.g., moving averages, stop-loss, RSI levels)

Use walk-forward validation or out-of-sample testing

Track Sharpe ratio, drawdown, and win rate

❌ Avoid:

Overfitting by blindly selecting the best-performing version

Using the same dataset for both training and testing

4. Backtest Across Different Market Regimes

Your strategy needs to work in more than one type of market.

✅ Do this:

Test in bull, bear, and sideways conditions

Use multi-year data to capture full cycles

Try different asset classes (BTC, ETH, SOL, etc.)

❌ Avoid:

Relying on a single environment or time period

Assuming recent performance equals future results

5. Validate With Forward Testing

A great backtest doesn’t guarantee real-world success.

✅ Do this:

Run your strategy live using paper trading or small capital

Compare live trades to your backtest performance

Look for signs of overfitting or market shifts

❌ Avoid:

Going live immediately based on one strong backtest

Ignoring feedback from current performance
