Handling Data Feeds

Import data into Backtrader by creating bt.feeds objects. You can use historical CSV files or data from online sources.

class MyStrategy(bt.Strategy):
def init(self):

def next(self): pass


Incorporating Technical Indicators

One of Backtrader’s strengths is its support for numerous built-in indicators, such as Simple Moving Averages (SMA) or Exponential Moving Averages (EMA).
