Sine wave indicator

[Jwabe]

Can anyone help me code a sine wave indicator.

It shouldn't be fancy, it should just draw the line that cycles up and down.

I have found many on the interwebz but they somehow follow the price and move around.

I just don't know where to start, even just a hint will help. My goal is to over lay this indicator over another. Thanks!

fxDreema cannot be used to code indicators but EAs only, sorry.
