Stochastic RSI cannot be negative

[bennycode]

Hi @codeplea, I have checked your Stochastic RSI implementation and was wondering why it becomes negative (-0.54) at the end of your "Example Calculation"? From what I have read on Investopedia the Stochastic RSI ranges only between 0 and 1: https://www.investopedia.com/terms/s/stochrsi.asp

Your tests actually show the same by expecting 0.000 at the end:

Lines 382 to 384 in 0bc8dfc

	stochrsi 5
	{81.59,81.06,82.87,83.00,83.61,83.15,82.84,83.99,84.55,84.36,85.53,86.54,86.89,87.77,87.29}
	{0.658,1.000,1.000,1.000,1.000,0.000}

So how come your website lists "-0.54"?

This seems to be an error with the website documentation. Thanks for letting me know. I'll make sure it gets fixed on the next update.
