How to set strategy's member externally

[Kas David]

How can I externally set a private member inside a strategy?

class strategy(bt.Strategy):
  def __init__(self):
    self.title = "how to set this externally?"

cerebro.addstrategy(strategy) # using strategy

cerebro.strategy.setTitle("new title")

Strategy instances are created during backtesting execution and not before.. What you need is to pass a parameter with your desired title.

Cool works for me, thanks.

class firstStrategy(bt.Strategy):
    params = (
        ('period',21),
        )
   x= self.params.period

cerebro.addstrategy(firstStrategy, period=14)
