 The Scan Engine allows users to create scans based on Daily, Weekly and Monthly bars. It does not support scans based on intraday (1-minute, 5-minute, etc.) bars. The Scan Engine allows users to create scans based on Daily, Weekly and Monthly bars.

-The first update for the Scan Engine usually begins at 9:31 AM Eastern Time. Because of the vast amounts of data involved, all scanning systems work with datasets that are slightly older than “real-time.” When the market is open, our Scan Engine is continually updating the final data point for all of the stocks and indexes that it tracks on a rotating basis. When an Extra or Pro member runs a scan based on the “Last Intraday Update,"​ the Scan Engine will use a final daily data point that may be up to three minutes old, depending on when the scan is run.+The first update for the Scan Engine usually begins at 9:31 AM Eastern Time.

-StockCharts ​Extra and Pro members can create and run their own custom technical scans with whatever technical criteria they want. We provide two different workbenches for creating custom technical scans - our Standard Scan Workbench and our Advanced Scan Workbench. Both workbenches are designed to help you quickly and easily construct custom scans by selecting pre-created scan clauses and adding them to your scan.+StockCharts members can create and run their own custom technical scans with whatever technical criteria they want.

 With the Advanced Scan Workbench, you can insert pre-created scan criteria into your scan from dropdown menus, then customize the criteria to suit your specific requirements. This provides a great deal of power and flexibility to create scans that are specially tailored for you, but does require a little bit of time and effort to master. For more information on using the Advanced Scan Workbench to create custom scans, please see our [[:​scans:​advanced_scan_workbench|Advanced Scan Workbench]] article in the Support Center. ​ With the Advanced Scan Workbench, you can insert pre-created scan criteria into your scan from dropdown menus, then customize the criteria to suit your specific requirements.

 While our original scanning tool, the Standard Scan Workbench, can be learned more quickly, it has some significant limitations when creating all but the simplest of scans and isn't recommended for everyday use. However, it can still be a good educational resource for users learning how to write scans. For more info on the Standard Scan Workbench and how to convert standard scans to advanced ones, please see our [[:​scans:​standard_scan_workbench|Standard Scan Workbench]] page in the Support Center. ​ While our original scanning tool, the Standard Scan Workbench, can be learned more quickly, it has some significant limitations when creating all but the simplest of scans and isn't recommended for everyday use.

-StockCharts also provides a large collection of Predefined Scans that we run throughout the day. The results from these predefined scans are available for anyone to review at no cost. In addition, ​Extra and Pro members can open the scans in the Advanced Scan Workbench to learn how they are constructed. A link to our predefined scan results is located on our Charts & Tools page.
