the I::Prices indicator allows you to reference prices from another
symbol.  For example, I wrote p/c ratio values into all of OHLC in a
db called FOO-PCR, and use {I:Prices CLOSE FOO-PCR} to refer to it.

This should be the same as above, however i think I::Prices only
supports different symbols in same timeframe ( and possibly requires
the data index to be same)
