[amibroker] An alpha indicator for bonds

["_sdavis" <_sdavis@xxxxxxxxx>]

I need some help with some metastock code taken from this URL:
http://www.traders.com/Documentation/FEEDbk_docs/Archive/0796/0796tradetips.html

What is the afl equivalent of this? Mostly I need to know what is the
"P" symbol? Everything else looks easy to translate to afl.

Mov((Sum(Log(C / Ref(C,-1)),9) - (((9*Sum(Log(C / Ref(C,-1)) * Log(P /
Ref(P,-1)),9)) - (Sum(Log(C / Ref(C,-1)),9) * Sum(Log(P / Ref(P,-1))
,9))) / ((9*Sum(Pwr(Log(P / Ref(P,-1)),2),9)) - Pwr(Sum(Log(P /
Ref(P,-1)),9),2)) * Sum(Log(P / Ref(P,-1)),9))) /9,12,SIMPLE)
