Hi

This mql5 code is not Shifting end of the chart from the right boarder. Any idea how2 get it done? Thank you

int OnInit() {
  //--- chart positioning
  ChartNavigate(0, CHART_END, 33);

The code is expected to place a distance of 33 bars between the right boarder of the chart and the latest price bar. But is not do it. 

It's missing two other function calls.

int OnInit() {
  //--- chart positioning
  ChartSetInteger(ChartID(),CHART_AUTOSCROLL,false);
  ChartSetInteger(ChartID(),CHART_SHIFT,false); 
  ChartNavigate(0, CHART_END, 33);

Edit:

Can't shift back further than CHART_END, it seems.

  Sleep(1000);
  ChartNavigate(ChartID(), CHART_END,  66);
  }

// Chart position
        ChartSetInteger(ChartID(),CHART_AUTOSCROLL,true);
        ChartSetInteger(ChartID(),CHART_SHIFT,true); 
        ChartSetDouble(0, CHART_SHIFT_SIZE, 22); //distance from right border
