ECN Broker Mystery

I use this OrderSend() code in ATC2007 Contest EA, MetaQuotes Demo, FXDD Live & IBFX Demo without problems (no errors). I started a Demo with a Swiss ECN Broker and I get "Error opening Sell order: 130".

Does anyone have idea as to why ??

int TakeProfit=100;
int StopLoss=100;
double tp,sl;
if(Sell1==1)
         {
         sl=0;
         tp=0;
         RefreshRates();
         if(StopLoss > 0) sl=NormalizeDouble(Bid+StopLoss*Point,Digits);
         if(TakeProfit > 0) tp=NormalizeDouble(Bid-TakeProfit*Point,Digits);
         ticket=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,sl,tp,"SELLSignal",MagicNumber,0,Red);
         if(ticket>0)
            {
            if(OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES)) Print("SELL order opened : ",OrderOpenPrice());
            }
            else Print("Error opening SELL order : ",GetLastError()); 
            return(0);
         }
