Add a variable in a strategy

[neo-13]

Good morning,
I created a strategy and all is okay, but at the beginning, I forget a variable and I would want to add a new variable.
I tried to write in the code and change the part "variable" and the part"properties" but don't work.
How do I do for this without create again a strategy please?

Thank's a lot for your help and scuse for my poor english, because I'm french.

Hello,

To make changes to your code, go to Tools -> Edit NinjaScript -> Strategy... -> Select the strategy you were working on and click OK.

If it was made with the Wizard, the Wizard will pop back up and allow you to make changes and add variables.

If the Code pops up you can add variables to the #region Variables section
It may look something like this
All the Variables go between the #region and #endregion
any lines with // are comments that are not read by the system

        #region Variables
        // Wizard generated variables
        private int myCustomIntVariable = 1; // Default setting for MyInput0
        // User defined variables (add any user defined variables below)
        private double myCustomDouble = 10.5;
        #endregion

Please let me know if I can be of further assistance.
