Input
Input Variables The input storage class defines the external variable. The input modifier is indicated before the data type. A variable with the input modifier can't be changed inside mql4-programs, such variables can be accessed for reading only. Values of input variables can be changed only by a user from the program properties window. External variables are always reinitialized immediately before the OnInit() is called.
Example:
//--- input parameters input int MA_Period=13; input int MA_Shift=0; input ENUM_MA_METHOD MA_Method=MODE_SMMA;
There is another way to set how your input parameter will look like in the Inputs tab. For this, place a string comment after the description of an input parameter in the same line. In this way you can make names of input parameters more understandable for users.
//--- input parameters input int InpMAPeriod=13; // Smoothing period input int InpMAShift=0; // Line horizontal shift input ENUM_MA_METHOD InpMAMethod=MODE_SMMA; // Smoothing method
input ENUM_MA_METHOD MAMethod = MODE_EMA;
// // Gives time frame as an input ... input ENUM_TIMEFRAMES Timeframe = PERIOD_CURRENT;
in adding input data to your advisors, indicators or etc, you can groups your input's together. for this following below descriptions:
int group "Moving Avarage Filter"
every inputs appears after this, attached to created group ...
