How to read from the indicator buffer values in a chart? - MQL4 and MetaTrader 4

ZZZEROXXX 2011.07.27 07:13 #151

Help with the code. We have a chart with an indicator with a buffer and a vertical line shifted to the past.

How to read from the indicator buffer values from the bar on which the vertical line is located to the end of the chart (zero bar)?

I wrote it like this:

tm=ObjectGet("VerticalLine",0);
for(x=iBarShift(Symbol(),0,tm);x==0;x--)
{
Print(x);
Print(Buffer[x])

}

It doesn't work, nothing is output at all. Help

tm=ObjectGet("VerticalLine",tm);
for(x=iBarShift(Symbol(),0,tm);x==0;x--)
{
Print(x);
Print(Buffer[x];

}

The problem must be in the line: tm=ObjectGet("VerticalLine",tm);

Read the Help, it needs something like: tm=ObjectGet("VerticalLine",OBJPROP_TIME1);

Sorry, I messed up, I wrote it by hand, in the original tm=ObjectGet("VerticalLine ",0); anyway, it doesn't work

if(ObjectFind("VerticalLine")!=-1){
    datetime TimeVL=ObjectGet( "VerticalLine", OBJPROP_TIME1); //получили координату времени где стоит вертикальная тиния с именем VerticalLine , которая сознательно  выставлена - так как не проверяется какая это линия и тд 
    int shift=iBarShift(NULL, 0, TimeVL); //получил смещение линииот текущего момента в свечах 
    
    //int c=Bars- shift; //если вдруг хочется до конца истории вывести значение индикатора (после линии)

    int c=10; // а это на скольких свечах после вертикальной линии анализировать значение индикатора
    for(int i=shift; i<=shift+c; i++){
     //double x=iCustom(NULL, 0, "СвойИндикатор", ..., int mode, i); // тут вроде как свой индикатор ....
     double x= iMA(NULL, 0, 12, 0, MODE_SMA, PRICE_CLOSE, i) ; // для примера вывод МА
     Print("x=",i," MA=",x);
    }
   }
   else Print("Нет Вертикальной линии");

- Be careful - the code will work tick by tick - you will get a lot of data for analysis :) on every tick the code is executed anew

That is, if I understood correctly what you want

In MQL, is it possible to make a binding to an indicator colour? I.e. when the indicator colour or indicator point changes, a position is opened.
