The quotepage Change value is computed as a difference in price from the Prev Close (Previous day's closing price) quotepage column. Some market data sources update this previous close value each time you log in, while others do not. Those that update it automatically should reliably show accurate Change, %Change, and Prev Close values.

If your data source does not supply this value, a custom column may be created to simulate the Change column. The Profession edition of Investor/RT is required to create a custom indicator to compute these values.

Investor/RT has long had the ability to add instruments to quotepages w/o having to open the quotepage to perform the addition. This is a somewhat hidden feature of the Quick Quote window.

Unless you do very long term weekly/monthly charting, click “Yes” to accept the recommended settings.

"Posting" is the process of recording the current daily prices (seen in the quotepage) into the daily database as the current daily bar. Posting Time is specified in the Session Preferences and is generally setup to occur a minute or two after the session closes. This process is not really needed in the end-of-day case. If you're just downloading your daily data after the session closes, you really have no need to "post".

Three Common Reasons that Long Term Composite Charts are not viewable

Here you can specify whether you wish to be prompted for a comment or not. If you elect NOT be to prompted, you have the further option of specifying "no comment" or a fixed comment of your choosing, e.g. "This RTL object compliments of Charles Dow".

The comment exported with the RTL object is displayed to the recipient when someone imports your scan, signal, or custom indicator.

Interactive Brokers historical backfill services can be unreliable but they do work. The problem with IB backfills is that IB is occasionally non-responsive to a download/backfill request. Additional requests have to be queued, awaiting the backfill in progress to complete. When IB is non responsive, the queue of awaiting requests essentially waits and waits and nothing appears to be happening at all. The DTN MA historical service is fast, accurate, highly responsive.

Yes. The file may be either a comma- or tab-separated text or csv file. The first line of the file is important and will tell Investor/RT that the following lines should be considered pairs or spreads (custom instruments). The first line should look like this:

/TYPE PAIR

The first line may also be used to tell Investor/RT that you would like to use division on the pairs instead of subtraction. The line above will default to subtraction, however, the line below:
