An achievement or a slump? : Why unemployment in the euro region is so high.
THE LATEST euro-region unemployment figures, discharged on July 31st, fulfill for gently perusing. They demonstrate the general unemployment rate has crawled down to 11.1% from its top of 12.1% in April 2013. Regardless of the uplifting news, another issue as long haul unemployment (for the most part characterized as being out of work for more than 12 months) has risen in the nineteen-part money union.

Means the function "void TrailingStop(int iTotal)" is not called inside start, init or deinit functions or their subfunctions.

phipho:

so i must do what?

 


void start()
  {
//---- check for history and trading
   if(Bars<100 || IsTradeAllowed()==false) return;
//---- calculate open orders by current symbol
   if(CalculateCurrentOrders(Symbol())==0) CheckForOpen();
   else                                    CheckForClose();

.....  you can try

void start()
  {
//---- check for history and trading
   if(Bars<100 || IsTradeAllowed()==false) return;
//---- calculate open orders by current symbol
   if(CalculateCurrentOrders(Symbol())==0) CheckForOpen();
   else{
       CheckForClose();
       TrailingStop(OrdersTotal());
       }
