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 the system is importent but your experience to read the market and take the right decision to refuse enter a trade
