What is Backtesting Frameworks

Backtesting frameworks are software tools that simulate trading strategies on historical price data, calculating performance metrics (returns, drawdown, Sharpe ratio) without real capital. Popular frameworks include Backtrader, VectorBT, Zipline, and QuantConnect. Backtesting identifies strategy edge before live trading, reveals transaction cost impact, and enables walk-forward analysis to detect overfitting. - Risk reduction: Test extensively before risking real money

❓ FAQ

▶What's backtesting?
Running trading strategy on historical data to evaluate performance before live trading.

▶What does Backtrader provide?

▶How do I avoid lookahead bias?
