What's the difference between a Signal and a Scan?
The difference lies in the context in which the two are used. Scans operate on current data, and can be used to:
- Find symbols within a given quotepage (and periodicity) that match a given criteria, or...
- Set properties or V# variables for all the symbols in a given quotepage...
A scan is sometimes called a "screen". A scan can either be run manually by the user, or be scheduled to run periodically.
