Possible bug in Chapter08/lib/data.py

[Eduardo Cobain]

Hi.

in line 33 it asks if prev_vals is not None but then it's not used.

if fix_open_price and prev_vals is not None:
                ppo, pph, ppl, ppc, ppv = vals

I think line 34 should be:
ppo, pph, ppl, ppc, ppv = prev_vals

Thanks.

I just came here to suggest exactly the same fix.
