Informational symbols are the symbols that may be required by the strategy's logic to make trading decisions.
For example, if the strategy's logic references S&P 500 Index to make trading decisions for 3M, the S&P 500 Index symbol must be listed in as an Informational symbol, in addition to the 3M symbol being listed as a Tradable symbol. Up to four informational symbols can be used for each tradable symbol; informational symbols must be listed in the '''data2''' through '''data5data10''' columns, in the same row as the tradable symbol for which they are intended.
