• Loading data into the platform

Data Feed Code Example:

data = bt.feeds.YahooFinanceData(...)

Executing Trades

Entering and Exiting the Market:

• Buy Signals: Short SMA crosses above Long SMA
• Sell Signals: Short SMA crosses below Long SMA

Order Execution Code Snippet:

def next(self): ...

Backtesting Your Strategy

Running a Backtest:

• Instantiate Cerebro engine
• Add strategy to Cerebro
• Run the backtest

Cerebro Setup Example:

cerebro = bt.Cerebro()cerebro.addstrategy(SampleStrategy)...

• Default Parameters: Detailed table showing parameter values
