These videos introduce Data Driven Investment Manager (DDIM) and are a guide to its use. Intended only as a temporary means of getting our beta users quickly up to speed, they are still a bit rough around the edges. Nevertheless, your feedback on them (via our forum) is greatly appreciated, and we expect to incorporate many of our beta users' suggestions in DDIM's formal public release. Our videos are posted on YouTube. Clicking on the video's title or the YouTube icon will open the page on which you can select an expanded view of the videos .
