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 ?

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).
