The majority of data providers have a limitation on the number of simultaneous real-time data subscriptions. This made scanning numerous markets almost impossible.The new version of our Scanner has two components: Pre-Scanning and Watchlist windows. You can scan more than 5000 symbols one by one with a specified frequency (every minute, 5 minutes, hour….) or just hit Rescan Now. According to your filters in Pre-Scanning instruments that satisfy the conditions will be shown in Watchlist window for updating in real-time.
<div style="background-color: #E3FBE5;">'''Note''': By default Autotrading is not supported in the Scanner window. Only indicators can be used. It is, however, possible to use the Scanner for trading in MultiCharts .NET. See how to do that in [https://www.multicharts.com/discussion/viewtopic.php?t=11028 this forum thread]. </div>

To open Pre-Scanning click the '''SHOW Pre-Scanning''' text at the top of the Scanner Window.
* The new scanner concept contains consists of two parts (see screenshots below):
# Watchlist (bottom window) that is a standard version of MultiCharts Scanner;
# Pre-Scanning (top window) that requests both historical and realtime snapshot data after a certain time interval pre-set by a user. The instruments satisfying the conditions can be copied into Watchlist.
