How to initialize indicators for each data in self.datas?

[thomaslee]

The following create errors

class PriceRelative(bt.Indicator):
    ''' x_t = Close_t/Close_{t-1} '''
    lines = ('PriceRelative', )
    
    def __init__(self):
        self.lines.PriceRelative = bt.indicators.RateOfChange(self.data.close, period=1)+1

class Test(bt.Strategy):

    def __init__(self):
        for a in self.datas:
            a.relative = PriceRelative(a.data.close)

How can i fix this so that I can initialize my indicator for each data.close?
