We currently use CSI,Metastock and ASC formats. We can read both end of day and intra-day data in these formats. The current product is a off line version so we don't have execution yet. We will be supporting execution as well as intra-day data feeds from various brokers as well as people like E-Signal in our Real time product later this year. Existing users will get a big discount on the product and be able to purchase it as an upgrade.
