How do I download data for the first time?
Read Getting Started With QCollector for a quick start guide to downloading data from IQFeed.
Why can't I see all the downloaded data records in the data window?
Only the the last 200 or so records are shown in the data grid because it would take too long to load all the data records for large data files. For ASCII data files you can use the Open File In External Editor feature to view all data records for an item. For MetaStock format data files use Edit MetaStock Records found under the symbol menu.
How many data files can I keep updated in real-time using the timed updates feature?
This will mostly depend on the speed of your computer but also on the bandwidth provided by your internet connection. When running timed updates QCollector can update several hundred data files in just a few seconds with a low-end computer and a 56k internet connection. With a high-end computer and high-speed internet connection, QCollector can update 500 or more files with the latest prices in less than one second.
Can QCollector update my data files automatically at the end of the day?
Yes. Use the Scheduled Tasks feature to schedule a data collection to occur every day after the markets close.
