Why do long term @ES# charts show different prices in prior months than other charting services?

Investor/RT uses DTN premium adjusted continuous contract historical data while other charting products are likely using the raw @ES# continuous contract historical data. The adjusted contract is premium adjusted so that charting of price on front month rollover days is smooth, no discrete gap up that has to do with time premium and little to do with market sentiment. We provide a means to turn off this default behavior in Investor/RT using a configuration variable.

How can I setup Investor/RT for automatic trading with Rithmic, CQG, or Gain? (Autotrading)

How do I change the default Account Balance Chart that comes up as part of the output of a backtest?

How do I import external historical data from a text or csv file?

The Import Window is accessible via the Data menu.

What is Fast Market Mode?

Fast Market Mode is available for extreme market conditions and is rarely needed by Investor/RT users due to efficiency improvements that have been made over time. In certain circumstances, it is possible for an extreme surge in volume to result in the program getting behind on the processing of ticks. During this situation, Fast Market Mode can be turned on in order to allow Investor/RT to quickly catch up. When Fast Market Mode is on, Investor/RT streamlines the reception of certain non-trade information (bid/ask changes).

How do I delete all my symbols except those in two user-defined quotepages.

You can do this manually, by opening the .All Symbols quotepage and deleting the symbols one at a time, by clicking on the ticker symbol in the quotepage and then clicking on the red trash can icon in the quotepage toolbar. You can delete ALL the symbols by clicking on the "Ticker" column heading and then clicking on the red trash can icon on the quotepage toolbar. However, that will remove the symbols from other quotepages as well.

You can create a scan (File > Open > RTL) as shown below:

If you run two copies of IB/TWS, how do you tell Investor/RT which one to connect to when you Start Data?

Each running copy of TWS has a Socket Port number used to communicate with 3rd party applications. Normally TWS is setup to listen for API connections on socket port number 7496. Leave one TWS setup with socket port 7496. Go to the other TWS and use the Configure Menu; Configure-->API-->Socket Port and enter some other port number, e.g 7497. In Investor/RT, use the IB Menu; IB-->Setup and set the Port setting to the socket port number of the TWS to which you wish to connect.

Text Variables (T# Variables)

The RTL language enables user text variables that can hold up to 30 characters of textual information. Each ticker symbol tracked by Investor/RT has its own set of 32 textual values. The RTL token names for these variables are T#1, T#2, ... T#32, analogous to the nomenclature for numeric V# variables. Like V#'s, any T# variable may be displayed in a quotepage and may be included in a quotepage format.
