Cool works for me, thanks.

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

cerebro.addstrategy(firstStrategy, period=14)

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")

Hello,
Does anyone have this indicator ported to backtrader?

Hmm, what's the next simplest thing I can do?

Hi, I'm new to backtrader, what's the simples way to plot debug lines?
eg. I want to display intermediate information based on an indicator, if possible without writing classes.

strategy:
def next(self):
    if self.adx[0] < 25:
      plot_addPoint(-1) # no trend
    else:
      plot_addPoint(1) # ongoing trend
