like to write the code for Mql4 of some indicator, so input values can be picked from a fix table
('extern int TF = 1,5,15,30,60,240,1440')
w/t the need to put explains or check the values entered.
this is practical for time frame entering, for instance.
any example of how it can be doen will be appreciated

not sure that i understand your question, but i liike to use the globalvariables to store/set variables...


see:

globalvariableget and globalvariableset functiions...

you can view all current global variables viia TOOLS -> VARIABLES or by pressing F3.


good luck.

thanks sister,
the user will pick the values from a preset list that will be shown in the Input window when he/she set the properties of the indicator. its should be like picking a color or logical value (true/false)

or, you could get really fancy and write a DLL that opens/runs a custom written windows application that has a data entry screen on it..

that would be cool..

that way, you would have complete control over the data entry process and the error checking of the entered data.

have fun.

i use dev-cpp to write my DLL's, download the one with the mingw stuff.

it is a free/donation optional windows C language ide and compiiler.

It's not possible without a custom library, however you can just use a string and let the user enter M1 or H4, parse the string in init.
