expected numpy.ndarray, got numpy.float64

[alizain5693]

I keep getting this error when using the candle stick patterns in talib. I'm passing in just float values and they should work fine. i tried typecasting them to nd arrays before passing but that didn't help. also I don't understand why the candle stick functions need nd arrays if they are asking for 4 o,h,l,c values. please help.

I'm using very simple version

//example

def bearish(o,h,l,c):
    return talib.CDLHANGINGMAN(o,h,l,c)

It looks like you are calling it with a scalar value not an array of values.
