The MarketDelta Blog

Here is a list of several steps you can take periodically to keep your MarketDelta running at at optimal level. Ideally, these steps should be done at least every 3 months, just like an oil change in your vehicle. For heavy users, we would recommend more frequent (every month).

1. Historical Data Preferences: Go to “Setup: Preferences: Historical Data” and make sure your data retention is minimal in reflection of your data needs. If using Footprint charts, keep in mind tick data is necessary.
2. Smart Compression: Enabling this option can greatly reduce your database size requirements (by over 80%). See this link on enabling it and pay special attention to the note about using this database feature.
3. Delete Unwanted Symbols: Open the “.All Symbols” system quotepage and use the red trashcan on the delete any unwanted or extraneous symbols from the system. Go to “Control: Database Wizard” and ensure “Compress Before Backup” is checked so the space occupied by the data of these deleted symbols will be recovered next backup and upon each backup.
4. Delete Charts / Other Objects: Delete any unwanted charts by going to “Control: Data Management: Object Editor: Charts”. In this window, other objects such as custom indicators, quotepages, or signals may be deleted. Ctrl- or Shift-click to perform multiple selection and deletion.
5. Delete Chart Elements: Click on the green trashcan on the chart toolbar to review the elements in a chart and delete any unwanted elements such as trendlines from many days in the past.
6. Check Recalculation Statistics: If you click this link, scroll down half way to see relevant information.
   Right-click in a chart and choose “Calc Statistics” and identify if any indicators are running inefficiently (taking too long to calculate and calculating too frequently). This is especially important if you feel your data is running behind.
7. Review Chart View Period: Bring up the charts preference windows and look in the “Period” tab to review the viewing period of each chart. Make sure the view period is set to load the data you want and need. Longer viewing periods can result in charts loading slower and indicators taking longer to calculate.
8. Full Maintenance and Backup Best Practices: Go to “Control: Database Wizard” (or Alt-U) and run Full Maintenance, followed by a Backup. If Full Maintenance reports database errors, you must correct those before proceeding. This page can be helpful in fixing a damaged database.
9. Floating and Hidden Windows: Sometimes windows get hidden or buried and you do not even know they are open. These extra windows consume resources. Click Window | Bring to Front and see if there are windows open or hidden that you do not need. If not needed, close them. Keep in mind windows marked “hidden” are windows open in other layouts and can be viewed using the layout toolbar.
