Graham,
This is by design. Foreign function MUST synchronize the data file
you are referencing with the currently selected symbol.
Synchronization makes sure that EACH bar of FOREIGN data
matches exactly with each bar of currently selected symbol
So if DateNum() function returns 990503 for given bar
then Close array represents the CLOSE of currently selected symbol at May 3, 1999
and Foreign("SYMBOL", "C") represents close of foreign symbol at May 3, 1999 TOO.
This is absolutely necessary because otherwise you won't be able
to do ANY meaningful operations involving both selected symbol and foreign symbol.
This also needed for the display so when you mark the quote with vertical
line it will always match the date displayed regardless if you use Foreign or not.
Otherwise you will end up in complete mess not knowing if data match or
not and what date is really represented.
Best regards,
Tomasz Janeczko
