<brVia Portfolio Tree it is also possible to import a list of tradable symbols from a CSV file: # Right-click the '''Instruments menu''' ->'''Import Instruments List'''# Select the required CSV file and click '''Open'''The symbols will be added to the Instrument List.
no edit summary
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 nine informational symbols can be used for each tradable symbol; informational symbols must be listed in the '''data2''' through '''data10''' columns, in the same row as the tradable symbol for which they are intended.
=== Adding Symbols to the Symbol List table ===
: <div style="background-color: #E3FBE5;">'''Note''': Informational symbols can only be added to a row that already contains a tradable symbol.</div>
: To add a symbol:
:# Select '''Move Down'''. A new row will be inserted. <br><br>
:A symbol can be copied from a cell using the CTRL+C keyboard shortcut, and pasted to a cell using CTRL+V keyboard shortcut. <br>The symbol can also be pasted to all cells of a column. To paste a symbol to all sells of a column, select the entire column by clicking the column header, and then paste the symbol to any of the selected cells.

==== Reload Data ====

Set '''Reload Data''' to '''Disabled''' to re-use the previous downloaded price data, and only load any new/missing data. If any other option is selected from the '''Reload Data''' dropdown list – the corresponding period of data will be reloaded.

==== Data Server Mode ====
Read about Data Server Mode settings [[Preferences#Data_server_mode|here]].
==== Use symbol cache for backtesting ====
Using cache is an alternative method to load symbol data. If cache is used, data is not pulled from the data source and is not renewed automatically.<br>
To refresh cache, press '''Clear cache''' and then run backtesting to upload the up-to-date data from the data source. The '''Clear cache''' button appears after the first backtesting in the current Portfolio instance, i.e. it is not displayed in a fresh Portfolio instance.<br>
When the option '''Use symbol cache for backtesting''' is disabled, Portfolio Trader uploads real-time data for the symbols.
