下面是我自己编的利用均线突破的交易程序， COMPILE 后，显示 '\end_of_program' - unbalanced left parenthesis 括号不配对 感觉问题是出在 //---Check for TralingStop---- 的那一段CODE 但我自己检查了好久， 也没法查出来， 只能请老师来帮我查错了， 先谢谢！ //+------------------------------------------------------------------+ //| MA Trend System.mq4 | //| | //| 突破长短期均线，趋势追随 | //+------------------------------------------------------------------+ #define MAGICMA 20050610 extern double Lots = 0.1; extern double TrailingStop = 70; extern double MaximumRisk = 0.02; extern double DecreaseFactor = 3; extern double MovingShort = 60; extern double MovingTrend = 240; extern double MovingShortMode = 0; //0=sma, 1=ema, 2=smma, 3=lwma extern double MovingTrendMode = 0; //0=sma, 1=ema, 2=smma, 3=lwma double MAshort; double MAtrend; //+------------------------------------------------------------------+ //| Calculate open positions | //+------------------------------------------------------------------+ int CalculateCurrentOrders(string symbol) { int buys=0,sells=0; //---- for(int i=0;i0) return(buys); else return(-sells); } //+------------------------------------------------------------------+ //| Calculate optimal lot size | //+------------------------------------------------------------------+ double LotsOptimized() { double lot=Lots; int orders=HistoryTotal(); // history orders total int losses=0; // number of losses orders without a break //---- select lot size lot=NormalizeDouble(AccountFreeMargin()*MaximumRisk/1000.0,1); //---- calcuulate number of losses orders without a break if(DecreaseFactor>0) { for(int i=orders-1;i>=0;i--) { if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)==false) { Print("Error in history!"); break; } if(OrderSymbol()!=Symbol() || OrderType()>OP_SELL) continue; //---- if(OrderProfit()>0) break; if(OrderProfit()<0) losses++; } if(losses>1) lot=NormalizeDouble(lot-lot*losses/DecreaseFactor,1); } //---- return lot size if(lot<0.1) lot=0.1; return(lot); } //+------------------------------------------------------------------+ //| Check for open order conditions | //+------------------------------------------------------------------+ void CheckForOpen() { int res; //---- go trading only for first tiks of new bar if(Volume[0]>1) return; //---- get Moving Average MAshort=iMA(NULL,0,MovingShort,0,MovingShortMode,PRICE_CLOSE,0); MAtrend=iMA(NULL,0,MovingTrend,0,MovingTrendMode,PRICE_CLOSE,0); //---- sell conditions if(Open[1]>MAshort && Close[1]MAshort && MAshort>MAtrend) { res=OrderSend(Symbol(),OP_BUY,LotsOptimized(),Ask,3,Ask-(Point*TrailingStop),0,"",MAGICMA,0,Red); return; } //---- } //+------------------------------------------------------------------+ //| Check for TralingStop conditions | //+------------------------------------------------------------------+ void CheckForClose() { //---- go trading only for first tiks of new bar if(Volume[0]>1) return; //---- for(int i=0;i(Point*TrailingStop)) { if(OrderStopLoss()< (Bid-Point*TrailingStop)) { OrderModify(OrderTicket(),OrderOpenPrice(),Bid-Point*TrailingStop,0,0,Green); return; } } } if(OrderType()==OP_SELL) { if((OrderOpenPrice()-Ask)>(Point*TrailingStop)) { if((OrderStopLoss()>(Ask+Point*TrailingStop)) { OrderModify(OrderTicket(),OrderOpenPrice(),Ask+Point*TrailingStop,0,0,Red); return; } } } } } //+------------------------------------------------------------------+ //| Start function | //+------------------------------------------------------------------+ 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(); //---- }

你代码里面有93个(，但是只有92个)，问题就在这里 if((OrderStopLoss()>(Ask+Point*TrailingStop)) 这里面多了一个(，去了就行了

昨晚花了一晚也没找出原因。 高手一点俺就明白了！ :handshake:handshake:handshake:handshake 在问个菜鸟问题， 括号配对是手工数的， 还是有工具可以自动查找的？ [ 本帖最后由 顶底背离 于 2006-5-2 22:58 编辑 ]

应该去调哪一个( ?

那一行最开始两个(，随便去掉一个就行了

hawkie 高手,羡慕

好想知道学此需要学习什么编程类的电脑书呢
