Hi , start with the positionGetSymbol for the index of the position in the list of positions.

It will automagically select the position for further analysis

int OnInit()
  {
  double exposure=getSymbolLots(NULL,false,false);
  Print("Exposure "+exposure);
  return(INIT_SUCCEEDED);
  }
void OnDeinit(const int reason)
  {
  }
void OnTick()
  {
  }

double getSymbolLots(string _symbol_or_null_for_all,
                     bool buy_only,
                     bool sell_only){
double lots=0.0;
//loop to all positions
  for(int i=0;i<PositionsTotal();i++){
     //get the symbol of the position at location i and select it too
       string positionsymbol=PositionGetSymbol(i);
       //if the position is of interest to us or we accept all symbols
       if(positionsymbol==_symbol_or_null_for_all||_symbol_or_null_for_all==NULL){
         //if its a buy and we want buys , its a sell and we want sells or we want both
           ENUM_ORDER_TYPE type=(ENUM_ORDER_TYPE)PositionGetInteger(POSITION_TYPE);
           if((buy_only&&type==ORDER_TYPE_BUY)||(sell_only&&type==ORDER_TYPE_SELL)||(!buy_only&&!sell_only)){
         //get lots
           lots+=PositionGetDouble(POSITION_VOLUME);
           }
         }
     }
return(lots);
};
