To see 
the plot just lay the code on 6701, to explore first select 6701 then choose 
"Current stock".. Note that viewing the  line may tell you more than the 
raw number in an exploration as it shows the trend (strengthening/weakening) of 
the study.....

Jayson and Ken.  Unfortunately, I cannot seem to makethe help file or 
this syntax work for me.  Let's assume I want to seethe correlation 
over the past 750 bars for Fujitsu and NEC (actuallythe case.  Their 
tickers are 6702 and 6701 respectively.  Can anyoneshow me how this 
should be written in an exploration?  I can't seemto turn the trick 
using 'foreign'.YukiSend BUG REPORTS to
