Raw or log prices as input?

[brunofacca]

Hello. Thank you for this library, it's been very useful to me.

Would you recommend using raw or log prices (OHLC) as input to generate all indicators? The question is not about whether raw prices or log prices are preferable in general, but if the formulas used to calculate the TA indicators in this library were written having raw or log prices in mind.

Raw, there are specific indicators making use of ln.
