double p1/*Maximum price*/ and p2;// Minimum Price

void OnChartEvent(const int id,const long& lparam,const double& dparam,const string& sparam)
  {
        if(id==CHARTEVENT_MOUSE_MOVE)
        {
         p1 = ChartGetDouble(0, CHART_PRICE_MAX);
         p2 = ChartGetDouble(0, CHART_PRICE_MIN);   
         Print(p1, " ", p2);
        }
 }

                                

The value is relative to the current view, if you scroll back, the value changes. Am trying to get the new value with the new code above but it is not working.

Thanks.
