StockRSI only returning NaN

[joaosauer]

Hi!

First of all, amazing library! You made a great job here.
My question is regards stockRSi indicator, that only returns NaN for me.
I was planning to use it for the bitcoin trades, but the coins that I'm using have very small values (this is the values of converted_to_list[1]):
<class 'tuple'>: (0.01411, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.01411, 0.01411, 0.01411, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.0141, 0.01411, 0.01411)

And then, independent of the period that I pass, the values are always NaN.
I'm calling: stochrsi.stochrsi([i * 1000 for i in converted_to_list[1]], len(converted_to_list[1]))
I tried to multiple the values by 1000, to make then more like your examples, but still gettin NaN.

Any idea why?

Many thanks,
Joao
