步骤 3 : BackTestController   
步骤 4 : view.html   

步骤 1 :

先运行,看到效果,再学习

edit
老规矩,先下载右上角的可运行项目,配置运行起来,确认可用之后,再学习做了哪些步骤以达到这样的效果。
先启动 EurekaServerApplication
跟着启动 IndexCodesApplication
然后启动 IndexDataApplication
接着启动 TrendTradingBackTestServiceApplication
随后启动 TrendTradingBackTestViewApplication
最后启动 IndexZuulServiceApplication
注: 记得运行redis-server.exe 以启动 redis 服务器
然后访问地址:

http://127.0.0.1:8031/api-view/

修改 ma 均线,看看不同均线会不会有不同的收益情况。
先运行,看到效果,再学习
在确保可运行项目能够正确无误地运行之后,再严格照着教程的步骤,对代码模仿一遍。
模仿过程难免代码有出入,导致无法得到期望的运行结果,此时此刻通过比较正确答案 ( 可运行项目 ) 和自己的代码,来定位问题所在。
采用这种方式,学习有效果,排错有效率,可以较为明显地提升学习速度,跨过学习路上的各个槛。

推荐使用diffmerge软件,进行文件夹比较。把你自己做的项目文件夹,和我的可运行项目文件夹进行比较。
这个软件很牛逼的,可以知道文件夹里哪两个文件不对,并且很明显地标记出来
这里提供了绿色安装和使用教程:diffmerge 下载和使用教程
步骤 3 :

BackTestController

edit
1. 增加对 ma 参数的接受
2. 把原来的 int ma 变量去掉
package cn.how2j.trend.web; import cn.how2j.trend.pojo.AnnualProfit; import cn.how2j.trend.pojo.IndexData; import cn.how2j.trend.pojo.Profit; import cn.how2j.trend.pojo.Trade; import cn.how2j.trend.service.BackTestService; import cn.hutool.core.date.DateUnit; import cn.hutool.core.date.DateUtil; import cn.hutool.core.util.StrUtil; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.CrossOrigin; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import java.util.*; @RestController public class BackTestController { @Autowired BackTestService backTestService; @GetMapping("/simulate/{code}/{ma}/{startDate}/{endDate}") @CrossOrigin public Map<String,Object> backTest( @PathVariable("code") String code ,@PathVariable("ma") int ma ,@PathVariable("startDate") String strStartDate ,@PathVariable("endDate") String strEndDate ) throws Exception { List<IndexData> allIndexDatas = backTestService.listIndexData(code); String indexStartDate = allIndexDatas.get(0).getDate(); String indexEndDate = allIndexDatas.get(allIndexDatas.size()-1).getDate(); allIndexDatas = filterByDateRange(allIndexDatas,strStartDate, strEndDate); float sellRate = 0.95f; float buyRate = 1.05f; float serviceCharge = 0f; Map<String,?> simulateResult= backTestService.simulate(ma,sellRate, buyRate,serviceCharge, allIndexDatas); List<Profit> profits = (List<Profit>) simulateResult.get("profits"); List<Trade> trades = (List<Trade>) simulateResult.get("trades"); float years = backTestService.getYear(allIndexDatas); float indexIncomeTotal = (allIndexDatas.get(allIndexDatas.size()-1).getClosePoint() - allIndexDatas.get(0).getClosePoint()) / allIndexDatas.get(0).getClosePoint(); float indexIncomeAnnual = (float) Math.pow(1+indexIncomeTotal, 1/years) - 1; float trendIncomeTotal = (profits.get(profits.size()-1).getValue() - profits.get(0).getValue()) / profits.get(0).getValue(); float trendIncomeAnnual = (float) Math.pow(1+trendIncomeTotal, 1/years) - 1; int winCount = (Integer) simulateResult.get("winCount"); int lossCount = (Integer) simulateResult.get("lossCount"); float avgWinRate = (Float) simulateResult.get("avgWinRate"); float avgLossRate = (Float) simulateResult.get("avgLossRate"); List<AnnualProfit> annualProfits = (List<AnnualProfit>) simulateResult.get("annualProfits"); Map<String,Object> result = new HashMap<>(); result.put("indexDatas", allIndexDatas); result.put("indexStartDate", indexStartDate); result.put("indexEndDate", indexEndDate); result.put("profits", profits); result.put("trades", trades); result.put("years", years); result.put("indexIncomeTotal", indexIncomeTotal); result.put("indexIncomeAnnual", indexIncomeAnnual); result.put("trendIncomeTotal", trendIncomeTotal); result.put("trendIncomeAnnual", trendIncomeAnnual); result.put("winCount", winCount); result.put("lossCount", lossCount); result.put("avgWinRate", avgWinRate); result.put("avgLossRate", avgLossRate); result.put("annualProfits", annualProfits); return result; } private List<IndexData> filterByDateRange(List<IndexData> allIndexDatas, String strStartDate, String strEndDate) { if(StrUtil.isBlankOrUndefined(strStartDate) || StrUtil.isBlankOrUndefined(strEndDate) ) return allIndexDatas; List<IndexData> result = new ArrayList<>(); Date startDate = DateUtil.parse(strStartDate); Date endDate = DateUtil.parse(strEndDate); for (IndexData indexData : allIndexDatas) { Date date =DateUtil.parse(indexData.getDate()); if( date.getTime()>=startDate.getTime() && date.getTime()<=endDate.getTime() ) { result.add(indexData); } } return result; } }
1. 创建变量 ma

ma:20,

2. 访问地址多了 ma

var url = "http://127.0.0.1:8031/api-backtest/simulate/"+vue.currentIndex+"/"+vue.ma+"/"+vue.startDate+"/"+vue.endDate+"/";

3. 参数增加 ma 下拉

<tr>
<td>
<span data-toggle="tooltip" data-placement="top" title="MA 即 moving average, 移动均线的意思。 比如MA20就表示20日均线,取最近20天的值的平均数">
MA(均线) :<span class="glyphicon glyphicon-question-sign " > </span>
</span>
</td>
<td>
<select class="form-control" @change="changeParam" v-model="ma">
<option value="5">5日</option>
<option value="10">10日</option>
<option value="20">20日</option>
<option value="60">60日</option>
</select>
</td>
</tr>
