Re: [amibroker] Looping / cache question

Hello,
 
1. No you don't need to do refresh. AmiBroker 'knows' already 
you have added the data
and will provide updated content.
 
2. RefreshAll via automation flushes the cache.
 
Hope this helps.

    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.

      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.
