Problem with custom Indicator

konny

Hi guys,

I'm trying to implement a indicator:

class IFT(bt.Indicator):

lines = ('ift',)
plotlines = dict(ift=dict(color='black', ls='-', linewidth=1.5))

def init(self):

  v = 0.1 * self.data
  self.l.ift = 100 * (np.exp(v) - 1) / (np.exp(v) + 1)

class testStrategy(bt.Strategy):

self.IFT = IFT(self.data)

TypeError: 'numpy.ndarray' object is not callable

Help will be appreciated.

Thanks
