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 size
11 lot=NormalizeDouble(AccountFreeMargin()*MaximumRisk/1000.0,1);
12 //--- calcuulate number of losses orders without a break
13 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 size
32 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。

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）。

昨天采用这套策略，抓到一个大行情，模拟盘赚了1万，实盘做的小，500美金的账号，每次下单0.01手，昨天一笔赚了10刀，把我昨天手动亏损的全赚回来了。
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
