MT4平台上mql4实现的基于macd指标的智能交易EA
屌丝命苦，拼爹拼不过，拼后台没有，技术宅一枚，情商有问题，不会见人说人话见鬼说鬼话，所以在国庆熬着混着，工作也没啥大起色，想想就郁闷，难不成一辈子就只能这样了？
苦思冥想，想得一条路，那就是程序化交易--现在程序化交易正有越来越火的趋势，国外已经程序化了很久，国内各大交易所也正在半掩半遮的开展，卷商、私人公司陆陆续续都在开展，心水啊，想着先研究研究，熟了之后也是碗饭啊，不行就靠着给人写策略也能吃口饭不至于饿死吧，想想还有点小鸡冻啊。
说干就干啊，原来做过外汇的模拟盘，用过MT4软件，软件自带MQL4语言，程序化已经支持的非常好了，还带有例子，还有高大上的名字叫EA，于是咱也高大上了一把，这年头都得将B格嘛。另外，选择外汇是因为外汇受认为操控的可能性比较小，外汇交易每天几万亿美元，不是个人能左右的了的。外汇里面，EUR/USD又是流通量最大的，所以就选择这个汇对。
废话了一大堆，直接在例子上改，开始是基于均线的MASample，运行了几个礼拜，不是很好，又在MACDSample上改了改，运行了个把月，基本上盈亏平衡，也算是个好开端吧。下面就是我该的macdSample的代码。
MQL4是一个类似c的语言，很多都可以按照c的逻辑来写。我定义的一些全局变量
1 input double TakeProfit =1000; 2 input double Lots =0.1; 3 input double TrailingStop =150; 4 input double MACDOpenLevel =5; 5 input double MACDCloseLevel=3; 6 input int MATrendPeriod =60; 7 input int MATrendPeriodFast =26; 8 input double MaximumRisk =0.08; 9 input double DecreaseFactor=3;10 input int CheckPeriod = 36;根据历史盈亏状况改变下单数量的函数，思路是：在最大下单数量的基础上*风险系数，如果有损失，损失次数/3,直到最小下单数量。不过最近也没用这个函数，主要是函数总是在几次损失后下最小的数量单子，但是行情总是在几次震荡才启动，所以总是错失良机，现在基本上都是下固定数量。
1 //+------------------------------------------------------------------+ 2 //| Calculate optimal lot size | 3 //+------------------------------------------------------------------+ 4 double LotsOptimized() 5 { 6 double lot=Lots; 7 int orders=HistoryTotal(); // history orders total 8 int losses=0; // number of losses orders without a break 9 Print("value of Lots:",lot);10 //--- select lot size11 lot=NormalizeDouble(AccountFreeMargin()*MaximumRisk/1000.0,1);12 //--- calcuulate number of losses orders without a break13 if(DecreaseFactor>0)14 {15 for(int i=orders-1;i>=0;i--)16 {17 if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)==false)18 {19 Print("Error in history!");20 break;21 }22 if(OrderSymbol()!=Symbol() || OrderType()>OP_SELL)23 continue;24 //---25 if(OrderProfit()>0) break;26 if(OrderProfit()<0) losses++;27 }28 if(losses>1)29 lot=NormalizeDouble(lot-lot*losses/DecreaseFactor,1);30 }31 //--- return lot size32 if(lot<0.1) lot=0.1;33 Print("lot:",lot);34 return(lot);35 }下面的函数是判断盘整行情的，主要是因为往往美国收市后，整个市场就波动很小了，等待第二天才会开始新一轮行情。
1 //判断从第i个行情之前的一段时间内存在盘整行情 2 //盘整行情的定义：行情波动不大 3 bool hasConsolidation(int i) 4 { double macd; 5 int count,j; 6 for(j=0;j<2*CheckPeriod;j++) 7 { 8 macd=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,i+j); 9 if(MathAbs(macd)<=(MACDOpenLevel*Point))10 {11 count=count+1;12 if(count>=CheckPeriod)13 {14 Print("isConsolidation:",2*CheckPeriod,"个周期内有连续半数以上波动过小");15 return true;16 }17 }else{18 count = 0;19 }20 }21 return false; 22 }MACD的基础理论来了，金叉和死叉的应用（关于MACD以及金叉死叉，这里不解释，请各位自行百度或者知乎），我这里判断一段时间内是否有金叉或者死叉，太长时间也没啥意义，我主要是基于5分钟线做日内交易。
1 //检查一小时内是否有金叉 2 bool CheckForGoldInHour() 3 { 4 double MacdCurrent,MacdPre,SignalCurrent,SignalPre; 5 for(int i=0;i<CheckPeriod;i++) 6 { 7 MacdCurrent=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,i); 8 MacdPre=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,i+1); 9 SignalCurrent=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,i);10 SignalPre=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,i+1);11 12 //在0轴下的金叉13 if(CheckForGold(MacdCurrent,MacdPre,SignalCurrent,SignalPre))14 return true;15 }16 17 return false;18 }19 20 bool CheckForDeathInHour()21 {22 double MacdCurrent,MacdPre,SignalCurrent,SignalPre;23 for(int i=0;i<CheckPeriod;i++)24 {25 MacdCurrent=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,i);26 MacdPre=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,i+1);27 SignalCurrent=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,i);28 SignalPre=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,i+1);29 30 //在0轴上的死叉. 31 if(CheckForDeath(MacdCurrent,MacdPre,SignalCurrent,SignalPre))32 return true;33 }34 35 return false;36 }37 38 bool CheckForGold(double MacdCurrent,double MacdPrevious,double SignalCurrent,double SignalPrevious)39 {40 if(MacdCurrent<0 && MacdCurrent>SignalCurrent && MacdPrevious<SignalPrevious && 41 MathAbs(MacdCurrent)>(MACDOpenLevel*Point))42 {43 Print("在0轴下的金叉");44 return true;45 }46 47 return false;48 }49 50 bool CheckForDeath(double MacdCurrent,double MacdPrevious,double SignalCurrent,double SignalPrevious)51 {52 if(MacdCurrent>0 && MacdCurrent<SignalCurrent && MacdPrevious>SignalPrevious && 53 MacdCurrent>(MACDOpenLevel*Point))54 {55 Print("在0轴上的死叉");56 return true;57 }58 59 return false;60 }所有的策略最后都归结到一点，你是看多还是看空，看多，平掉空单，开多单，看空，平掉多单，开空单，简单的逻辑。
1 double Macd0,Macd1,Macd2; 2 double Signal0,Signal1,Signal2; 3 double Ma0,Ma1,Ma2; 4 double highLevel; 5 6 // 看前三个macd值和signal,都是向上的，并且均线向上 7 bool CheckForLong() 8 { 9 Macd0=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,0);10 Macd1=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,1);11 Macd2=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_MAIN,2);12 13 14 Signal0=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,0);15 Signal1=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,1);16 Signal2=iMACD(NULL,0,MATrendPeriodFast,MATrendPeriod,9,PRICE_CLOSE,MODE_SIGNAL,2);17 18 19 20 if(Macd1>=Macd0 || Macd2>=Macd1 || Signal1>=Signal0 || Signal2>=Signal1)21 {22 Print("CheckForLong:macd或者signal不是向上");23 return false;24 }25 26 highLevel = (Macd0+Macd1+Macd2-Signal0-Signal1-Signal2)/3;27 28 if(highLevel<MACDOpenLevel*Point)//Macd0<=(Signal0+MACDOpenLevel*Point) || Macd1<=(Signal1+MACDOpenLevel*Point) || Macd2<=(Signal2+MACDOpenLevel*Point))29 {30 Print("CheckForLong:macd不满足开仓必须高于信号足够的量");31 Print("相差",highLevel/Point,"个Point");32 return false;33 }34 35 //均线变动比较慢，暂时取两个36 Ma0=iMA(NULL,0,MATrendPeriod,0,MODE_EMA,PRICE_CLOSE,0);37 Ma1=iMA(NULL,0,MATrendPeriod,0,MODE_EMA,PRICE_CLOSE,1);38 //Ma2=iMA(NULL,0,MATrendPeriod,0,MODE_EMA,PRICE_CLOSE,2);39 if(Ma0<Ma1)// || Ma1<Ma2)40 {41 Print("CheckForLong:均线向下，没有向上");42 return false;43 }44 45 if(!CheckForGoldInHour())46 {47 Print("CheckForLong:有效时间内没有检测到0轴下的金叉");48 if(hasConsolidation(0))49 {50 Print("CheckForLong:检测到盘整行情，现在已经确定走势，可以开仓。");51 return true;52 }53 return false;54 }55 56 //if(Macd0>Macd1 && Macd1>Macd2 && Signal0>Signal1 && Signal1>Signal2 && 57 // Macd0>(Signal0+MACDOpenLevel*Point) && Macd1>(Signal1+MACDOpenLevel*Point) && Macd2>(Signal2+MACDOpenLevel*Point)58 // && Ma0>Ma1)59 //{60 //检查一小时内有金叉61 // if(CheckForGoldInHour())62 // return true;63 //}64 65 //Print("CheckForLong:long");66 return true;67 }这里面加入了均线的判断，macd本质上就是依据两条不同步调（比如我选择的26日均线和60日均线）的均线，如果快的均线离慢均线越来越近，则代表行情可能结束。但是在实际情况中，经常会是，快均线在超过慢均线快速上涨之后，慢慢回落到慢均线，等于慢均线快接近的时候，又快速拉升，慢均线就像支撑线。但是如果仅仅就macd的理论，行情在两均线靠近时就已经要反转了，而这往往是错误的判断。所以macd往往要配合均线。我这里采用26日均线来判断趋势，对于看涨函数，只有在均线是向上的时候才会开仓。同理，下面的short判断也是要看均线向下才开仓。

下面就是ontick函数，相当于c语言的main函数，主要是根据多空的判断来开仓和平仓，还有就是移动止损，有点复杂，但是其实也就是一句话的事，就是采用60日均线来作为移动止损点，默认止损是120点，之后取120点和60日均线的大值（要有足够的行情波动空间）。

当时也是看模拟盘，模拟的不错，一激动入了金，结果发现，外汇还真不是好的发财门道。目前电脑做的比我好多了
