This Backtrader example demonstrates a simple moving average crossover strategy and how cheat-on-open mode changes the timing of order decisions. It builds two moving averages, with configurable periods and moving-average type, then uses their crossover as…

This example shows how to replay lower-timeframe price data as daily, weekly, or monthly bars in Backtrader. A simple strategy calculates a configurable simple moving average and prints lifecycle messages as the replayed data advances. The script lets users…

This Backtrader example demonstrates managing several data feeds independently within one strategy. It assigns entry and holding weekdays by data-feed index, tracks each feed’s position and outstanding orders, and sizes buys and sells differently through a…

This Backtrader example demonstrates how to load minute-level CSV data for a chosen date range and trading session, optionally filter records to session hours, and fill missing bars within that session. The filler can assign a configurable volume to…

This Backtrader example defines a signal strategy using a fast and a slow simple moving average, with configurable periods. A crossover drives long entries; an option enables long-short signals. The script loads historical data, sets starting cash and…

This Backtrader example shows how a strategy can use two data feeds: a moving average crossover on the second asset generates long entry and exit signals, while orders are placed on the first. The signal uses a simple moving average and a crossover of the…
