DDEChartUpdater allows you to use MetaStock (http://www.equis.com) or SierraChart (http://www.sierrachart.com) with data feeds that are not supported originally. The program connects to external programs providing (real-time) quotes via Windows DDE. DDEChartUpdater converts these quotations to MetaStock or SierraChart format. The charts of MetaStock/SierraChart will be refreshed automatically. More features of DDEChartUpdater: You can download data from any source in DDE format directly to MetaStock or SierraChart format. This widens the selections of possible data vendors by several orders of magnitude. You can use as many data vendors as you want. So you can easily combine the advantages of these venders by just configuring the DDEChartUpdater.
