MQL4 Indicator passing signal to EA

Question

the problem is, I want to open order when my indicator gives signal. How can I do that?

I have been trying to do with iCustom() but it is not satisfying.

I tried to use GlobalVariableSet() in indicator and GlobalVariableGet() method in EA but it is not properly worked.

Please help.

The syntax is:

double  iCustom(
   string       symbol,           // symbol
   int          timeframe,        // timeframe
   string       name,             // path/name of the custom indicator compiled program
   ...                            // custom indicator input parameters (if necessary)
   int          mode,             // line index
   int          shift             // shift
   );

Here is the example using custom Alligator indicator (which should be available by default as Alligator.mq4 in MT platform).

double Alligator[3];
Alligator[0] = iCustom(NULL, 0, "Alligator", 13, 8, 8, 5, 5, 3, 0, 0);
Alligator[1] = iCustom(NULL, 0, "Alligator", 13, 8, 8, 5, 5, 3, 1, 0);
Alligator[2] = iCustom(NULL, 0, "Alligator", 13, 8, 8, 5, 5, 3, 2, 0);

where 13, 8, 8, 5, 5, 3 are corresponding input parameters of custom Alligator as defined in indicator it-self:

//---- input parameters
input int InpJawsPeriod=13; // Jaws Period
input int InpJawsShift=8;   // Jaws Shift
input int InpTeethPeriod=8; // Teeth Period
input int InpTeethShift=5;  // Teeth Shift
input int InpLipsPeriod=5;  // Lips Period
input int InpLipsShift=3;   // Lips Shift

and mode is the corresponding line index as defined in the indicator by:

SetIndexBuffer(0, ExtBlueBuffer);
SetIndexBuffer(1, ExtRedBuffer);
SetIndexBuffer(2, ExtLimeBuffer);
