Common Backtesting Mistakes
| Mistake | Impact | Fix |
|---|---|---|
| Test only in bull market | Overestimates returns | Test in bull, bear, sideways, and crash periods |
| Ignore fees | Overstates profit by 2-3% | Include exchange fees (0.02-0.1%) in calculations |
| Too short test period | Not statistically significant | Test minimum 3 months, ideally 6-12 months |
| Over-optimize | Settings work in past but not future | Test on one period, validate on another |
| Ignore slippage | Real results differ from backtest | Assume 0.05% slippage per trade |

FAQ: Crypto Bot Backtesting
Q: What is crypto bot backtesting?A: Backtesting runs your bot strategy against historical price data to see how it would have performed. You test settings like base order, safety orders, and take profit against months of real market data before risking real money.
Q: How accurate is backtesting?A: Backtesting is 85-95% accurate when done correctly (including fees, slippage, and testing across multiple market conditions). Real results may vary 1-3% from backtest due to slippage and fee differences.
Q: How long should I backtest a crypto bot?A: Minimum 3 months of historical data. Ideally 6-12 months covering bull, bear, sideways, and volatile periods. The more data you test, the more confident you can be in the results.
Q: Can I backtest on 3Commas for free?A: Yes. 3Commas paper trading mode is available on the free plan. You can test strategies with simulated money using real market data. For historical backtesting, set the bot start date to a past period.
Q: Does backtesting guarantee future results?A: No. Backtesting shows how settings WOULD have performed historically. Future markets differ from past markets. However, backtested strategies are far more reliable than untested settings — 30-50% better on average.
