mql4 iLowest() 给出了错误的蜡烛 ID？

Question

I am trying to get the lowest candle ID inside for loop

Use case:

Step 1: i am using for loop to check candle ID of the candle on which the indicator is visible most recently, and then break the loop

Step 2: i am using iLowest() to get the candle ID of the bar having the lowest value out of 5,

Step3: using the candle id (from step 2) to get low value of that candle and then calculate the SL for that candle.

But i am getting wrong ID of candle in Step 2.

please have a look at the below screenshot, the comment of bar should be 74 but it shows 135

Here is my code:

   for(int i=0;i<1000;i++)
           {
          double btt1= iCustom(NULL,0,"Arrows",0,i);
          double btt2= iCustom(NULL,0,"Arrows",1,i);
          if(btt1!=EMPTY_VALUE)
            {
             if(Digits==5|| Digits==3)
                   {
                    baar =iLowest(NULL,0,MODE_LOW,5+i,i);
                    lowestb = Low[baar];
                    stoploss = lowestb- 20*Point*10; 
                    Comment("value of i :  ",i,"    value of baar :  " , baar );
                     ObjectCreate(chart_ID,name,OBJ_LABEL,sub_window,0,0);
                     ObjectSetInteger(chart_ID,name,OBJPROP_XDISTANCE,xx1x);
                     ObjectSetInteger(chart_ID,name,OBJPROP_YDISTANCE,yy1y);
                     ObjectSetInteger(chart_ID,name,OBJPROP_CORNER,corner); 
                     ObjectSetString(chart_ID,name,OBJPROP_TEXT, stoploss   ); 
                     ObjectSetString(chart_ID,name,OBJPROP_FONT,font); 
                     ObjectSetInteger(chart_ID,name,OBJPROP_FONTSIZE,font_size); 
                     ObjectSetInteger(chart_ID,name,OBJPROP_COLOR,clrRed);            
                     ObjectSetInteger(chart_ID,name,OBJPROP_BACK,back);
 
                   break;
                   }
                  
                   }
                   
                   }

What am i doing wrong?

Answer 1

Change it to:

baar =iLowest(NULL,0,MODE_LOW,5,i);

Because the 4th parameter of the iLowest function counts the number of bars that you want to analyze starting from the counter i (the last parameter).
