MQL4参考自定义指标 SetIndexShift

SetIndexShift

Sets offset for the drawing line.

void  SetIndexShift(
   int     index,       // line index
   int     shift        // shift
   );

Parameters

index

[in] Line index. Must lie between 0 and 7.

shift

[in] Shift value in bars.

Returned value

None.

Note

For positive values, the line drawing will be shifted to the right, otherwise it will be shifted to the left. I.e., the value calculated on the current bar will be drawn shifted relatively to the current bar.

Example:

//+------------------------------------------------------------------+
//| Alligator initialization function                                |
//+------------------------------------------------------------------+
int init()
  {
//---- line shifts when drawing
   SetIndexShift(0,JawsShift);
   SetIndexShift(1,TeethShift);
   SetIndexShift(2,LipsShift);
//---- first positions skipped when drawing
   SetIndexDrawBegin(0,JawsShift+JawsPeriod);
   SetIndexDrawBegin(1,TeethShift+TeethPeriod);
   SetIndexDrawBegin(2,LipsShift+LipsPeriod);
//---- 3 indicator buffers mapping
   SetIndexBuffer(0,ExtBlueBuffer);
   SetIndexBuffer(1,ExtRedBuffer);
   SetIndexBuffer(2,ExtLimeBuffer);
//---- drawing settings
   SetIndexStyle(0,DRAW_LINE);
   SetIndexStyle(1,DRAW_LINE);
   SetIndexStyle(2,DRAW_LINE);
//---- index labels
   SetIndexLabel(0,"Gator Jaws");
   SetIndexLabel(1,"Gator Teeth");
   SetIndexLabel(2,"Gator Lips");
//---- initialization done
   return(0);
