RSI to oscilate around zero?

This might sound really stupid (and its not important anyway) but does anyone have an RSI which oscillates about 0 instead of 50.Just thought I could clear the charts as my two indicators MACD and RSI would then fit nicely in 1 window.

Thanks,

Ed.

Here you go. Took me thirty seconds to modify the RSI that comes with MT.

As you can probably tell programming isnt my forte.

No problem, the "30 second" remark wasn't meant so much for you as it was for the 20 people who are going to read this thread and ask me if I'll make their indicator for free. I'm pretty willing to do it if it takes less than a minute, anything above and beyond and I start to balk.
