The Instrument Editor tool is divided in three functional parts: Instruments, Instrument Properties and Add an Instrument.
The Instruments panel shows a list of all the symbols set in Forex Strategy Builder. You can change the position of a symbol by moving it up or down. You can also delete any of the presented symbols except the current instrument loaded in the program and the EURUSD symbol. By double clicking on a symbol, you load it in the Instrument Properties panel.
In the Instrument Properties panel you can set or change the parameters of the currently selected symbol. When you are ready, press “Accept” button.
You can add new symbols to the program by using the Add an Instrument panel. After pressing the Add button, the symbol appears in the list of Instruments and in the Instrument Properties panel. You have to “Accept” the changes made to this symbol before closing the tool window.
