Fast Stochastic with low period

oakenstream

Hey,

I want to use the fast stochastic's K value and check when that one crosses under 10 from a strategy in a book. I'm doing this:

self.inds[d]['faststoch'] = bt.indicators.Stochastic(d, period= 2)

and I'm geting this:

ZeroDivisionError: float division by zero

the definition of the fast stochastic is I beleive:

%K = (C – L) / (H – L) * 100
%D = 3 days smoothing

I would like only to use the %K value. Is this possible?
