Along
those lines TJ: If I import a ticker via automation should I do a
Refresh?

If I
do a refresh via automation does that flush the cache?

Looping / cache question
Chuck,
No, data are read from the cache regardless of the fact that
you are using Foreign.
But.. only when:
(1) they are already in the cache
(2) they were not flushed by other symbols data because of
two small cache size
(3) they do not have refresh pending (becuase of real time
streaming update)
I hope this answers your question. Have a nice
day.
Best regards,Tomasz Janeczkoamibroker.com

Subject: [amibroker] Looping / cache
question
<FONT face=Arial color=#0000ff

this board as it may slip past unnoticed. I feel that the question and
answer may be important to others in this
group.

<FONT face=Arial color=#0000ff
size=2>When looping through tickers (using Foreign), data seems to always be
read from files rather than from cache. If I have "normal" afl
that simply processes all of the tickers in a watchlist, the first pass
through the watchlist reads from files and subsequent passes read from
cache. If I loop through those same tickers in a watchlist using
a Foreign statement, the data seems to be read from files for every
pass.

Is
my understanding correct?

Is
this an area for possible future improvement?
