hey guys, i'm trying to port some code to NT but my Easy Language knowledge is holding me back.
can someone explain what the "Log" term is doing here so i can write something for ninjascript?
Data = 0.25*Log((1+Value)/(1-Value));
what is "Log" doing here?
Data= is current bar equals
0.25*Log is one quarter of whatever log(?) is
( Value) is a number between .9999 and -.9999 so
(1+Value)/(1-Value) is a positive number (ratio) between 20,000 and .00005
thanks in advance for any help

so if there was a piece of EasyLanguage code that was
Data = 0.25*Log((1+Value)/(1-Value));
would that be base 10 or base e?
what would the default be, i guess is my question?

It's the natural logarithm, so base e.
