[amibroker] Re: How To Force IQFeed Backfill For All Symbols

["sidhartha70" <sidhartha70@xxxxxxxxx>]

Set up a watchlist of all your symbols and run a scan or exploration across that watchlist.... doesn't matter what the scan/exploration does... but choose 'wait for backfill' in the automatic analysis window... once symbols are backfilled, they will will continue streaming (all of them) so you will not need to backfill again that session.

I have noticed some large holes in my data when my computer is off during the market open hours. The only way I have found to fix this problem is to select an individual symbol and select Force Backfill from the IQFeed plugin menu. At first, I used a Scan with Wait for Backfill checked on, and this worked well to get the initial set of data for all my symbols. However, it is no longer working to fill those holes since I have all the symbols in a Realtime Quote window and now all the symbols have the latest data while my computer is on.
