# '''Compared value''' input field.

===Selection of Scanning Criteria===

Criteria toolbar represents a statement with adjustable clauses that allow customization of the scanning criteria:

* '''and use constrain''' checkbox. When checked a constrain condition will be applied. This condition is designed to compare the prices and indicator values with the pre-set ones.

**After checking '''and use constrain''' checkbox select a price or indicator value, comparison type and compared value.

===Starting Pre-Scanning===

When instruments are added into Pre-Scanning Part of the Scanner Window and the pre-scanning criteria is set, scanning can be started. To start scanning click the '''Rescan now''' button.

===Scanner Window Status Line===

Status line shows:

* Data source name

* If '''and every''' checkbox is enabled historical scanning will be repeated in the set period of time. In this case, the countdown until the next scan will be shown in the Scanner Window status line.

===Working with Scanner in offline mode===

In order to speed up the process of historical scanner backfill in offline mode the instrument will be unsubscribed after either complete historical data backfill or after a certain timeout thus letting the other instruments be backfilled sooner.
