I was demonstrating to a friend of mine how to use RTD with Ami. I logged in to NEST with his ID, checked all the settings for NEST and VWAP and Data Table. Then I started RTD and Ami was automatically started, though it took few seconds more that it did with my ID. Then when I did "Do Backfill", the DT was opened and in the backfill winodw it said backfilling and also completed backfill. But there was no data for that day in Ami. So does this mean that the ID with which we login to NEST is also somehow important? While doing backfill with new ID, the name TATASTEEl disappeared from the backfill window where it says "Select symbol to backfill"
Then I again logged in with my ID and did backfill, and data of that day appeared.
