Detailed explanation of iCustom - page 4

Hello, i have a quick (and painless, i hope) question about iCustom: let's say that i have 3 indicators called Ind_A, Ind_B and Ind_C, and i have an Expert Advisor called EA.

the EA calls all the 3 indicators using icustom, passing their arguments and getting the results by indexing their respctive buffers.

i attach my 3 indicator on the EURUSD chart and i run my EA; let's focus on the indicator Ind_A, he is running as indicator but at the same time is executed by the EA: the instance is the same or we have two instances of ind_A running? (i mean, one instance runs on his own and the other instance lives inside the EA).

in suche case, each instance has his own buffer? or is the buffer shared between all the instances of the indicator?

Many thanks!

Sorry to wake up this thread again. But I thought my question belongs to this topic. 

I try to access 2 buffers from a custom indicator trend-target, the indicator has one input = 60, and two buffers Band UP and Band LO

using

double Value1 = iCustom(Symbol(),0,"TrendTarget.ex4",60,0,1,0);



double Value2 = iCustom(Symbol(),0,"TrendTarget.ex4",60,0,0,1);double Value1 = iCustom(Symbol(),0,"TrendTarget.ex4",60,0,1,0);



Comment("iCustom returned v1= "+Value1+ " and value2= ",Value2);

  is the way I set parameters for this iCustom correct? because I seem not to get the Band Up and Band LO values not exact to the buffers in data watch panel pls check the attached picture. Only the 2 or 3 first decimal digits or 3e right but for a FX quote all 4 digits must be correct is it right?

I hope the coder and experienced users on MQL5 can help me quickly correct this issue? Thanks in advance

Apropos what is your indicator has 5 inputs and 4 buffers,

double Value1 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,1,0,0,0);

double Value2 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,2,0,0);

double Value3 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,3,0);

double Value4 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,0,4);

Like this above?

double Value1 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,1,0,0,0);
double Value2 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,2,0,0);
double Value3 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,3,0);
double Value4 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,0,4);

Absolutely not.

iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,BufferIndex,BarIndex);

double value1 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,1,0,0,0,0); //with BarIndex=0, when only check on close or 1= when check on every tick;
double value2 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,1,0,0,0);
double value3 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,1,0,0);
double value4 = iCustom(Symbol(),0,"indicator",a1,a2,a3,a4,a5,0,0,0,1,0);

thank you for your correction I just found an example " Combined Use of Programs" (https://book.mql4.com/samples/shared) in mql5 I think that example in codig is what I need. I will study that part, if have question in my programing I hope you would help me to get it run getting more stable and more profit 

I have the code this way now I cn see the buffers 1, 2 of the TrendTarget (But still not all 4 digits correct!!!), I set the BarsIndex value on every stick to  1 because I like to recheck the TrendTarget 

   double shortSma, longSma, ShortSL, ShortTP, LongSL, LongTP,Band_UP,Band_LO;

   double Value1,Value2 ;





   Value1 = iCustom(Symbol(),0,"TrendTarget.ex4",60,1,1);

   Value2 = iCustom(Symbol(),0,"TrendTarget.ex4",60,2,1);

   Band_UP = Value1;

   Band_LO = Value2;

   Comment(" !!!!!!! ICUSTOM returned Value1= "+Value1+ " and value2= ",Value2+"\n");

if(tik <= 5 && Ask>Band_UP) ///////////////ONLY can open SELL////////////////
        {
         ////////////////////// TP1 SL1 ///////////////////////////////////
         openOrder(Symbol(), OP_SELLSTOP,LotSize,sellPrice,sellPrice+SL1*point(), sellPrice-TP1*point(),"_Sell_1",MagicNumber,exp,Crimson);
        }

      if(tik <= 5 && Bid<Band_LO)   ///////////////ONLY can open BUY////////////////

        {
         ////////////////////// TP1 SL1 ///////////////////////////////
         openOrder(Symbol(), OP_BUYSTOP,LotSize,buyPrice,buyPrice-SL1*point(), buyPrice+TP1*point(),"_Buy_1",MagicNumber,exp,Navy);
        }
