Get user input?

New comment
 

How do you get user input for the external variables here?

Also, what is the function to have the message box say OK, rather than YESNO?

Maybe I get you wrong, but let's say:


1. Like every extern variable is avaible for user:


extern double InputtedStopLoss=50;
extern double InputtedAccountCapital=3000;
extern double InputtedRisk=1.5;


those are 3 inputs from your code.


2. in your message box:

MessageBox(text, "Lot size", MB_YESNO|MB_ICONQUESTION);


you need to change into


MessageBox(text, "Lot size", MB_OK|MB_ICONQUESTION);

Hi

Yes, but when I run the script, it doesn't ask for the external variables, the script just runs. I wanted it to come up with a box so I could enter these 3 variables (if they need changing from the default) and run the script.

 

refer here #property show_inputs
