Step-by-step procedure
Per the procedure infobox.
Libraries
- backtrader (Python): Full backtesting framework.
- vectorbt (Python): Vectorized fast backtests.
- Custom code: Pandas + NumPy for simple strategies.
Common pitfalls
- Lookahead bias: Using future data in signal generation.
- Survivorship bias: Only testing on currently-listed stocks.
- Optimistic fills: Assuming you got the closing price always.
- Ignoring slippage: Real fills differ from candle close.
- Ignoring costs: Brokerage, STT, exchange fees materially affect P&L.
Walk-forward validation
Train on 60-70% of data, test on rest. Avoid over-fitting.
Risk
Past performance doesn’t guarantee future results. Backtest results are not investment advice. For complex strategies with significant capital, consult a SEBI-registered Investment Adviser.
