Answer 1

Will be faster with numpy.

 def HEIKIN(O, H, L, C, oldO, oldC):
     HA_Close = (O + H + L + C)/4
     HA_Open = (oldO + oldC)/2
     elements = numpy.array([H, L, HA_Open, HA_Close])
     HA_High = elements.max(0)
     HA_Low = elements.min(0)
     out = numpy.array([HA_Close, HA_Open, HA_High, HA_Low])  
     return out
