利用Warensoft Stock Service编写高频交易软件

无论是哪种交易软件,对于程序员来讲,最麻烦的就是去实现各种算法。本文以SAR算法的实现过程为例,为大家说明如何使用Warensoft Stock Service来实现高频交易软件的快速开发。

目前WarensoftStockService已经实现了C# 版本的客户端驱动,可以直接在Nuget上搜索Warensoft并安装。客户端驱动已经编译为跨平台.net standard1.6版本,可以在桌面应用(WPF,Winform)、Xamarin手机应用(WP,Android,IOS)、Web(asp.net,asp.net core)中应用,操作系统可以是Window,Android,IOS,IMAC,Linux。

下面将以Android为例(注:本Demo可以直接平移到WPF中),说明SAR指标的实现过程,其他指标计算的综合应用,在其他文章中会专门讲解。

软件环境说明

IDE

VS2017 RC

客户端

Android4.4

服务器环境

Ubuntu16

客户端运行环境

Xamarin.Forms

客户端图形组件

Oxyplot

建立一个Xamarin.Forms手机App

这里选择基于XAML的App,注意共享库使用PCL。

添加Nuget引用包

首先,为Warensoft.StockApp共享库添加Oxyplot引用(此处可能需要科学上网),如下图所示:

然后再分别安装Warensoft.EntLib.Common,Warensoft.EntLib.StockServiceClient,如下图所示:

然后为Warensoft.StockApp.Droid添加OxyPlot的NuGet引用,如下所示:

然后在Android的MainActivity中加入平台注册代码:

OxyPlot.Xamarin.Forms.Platform.Android.PlotViewRenderer.Init();

MainActivity.cs的代码如下所示:

protected override void OnCreate(Bundle bundle)
 {
 TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
OxyPlot.Xamarin.Forms.Platform.Android.PlotViewRenderer.Init();
 base.OnCreate(bundle);
 global::Xamarin.Forms.Forms.Init(this, bundle);
 LoadApplication(new App());
 }

实现主窗口

主界面的实现采用MVVM模式来实现,关于MVVM的讲解,网上应该有很多了,后面的文章中,我会把我自己的理解写出来,让大家分享。本DEMO的MVVM框架已经集成在了Warensoft.EntLib.Common中,使用起来很简单。

第一步:

编写主界面(需要了解XAML语法),并修改MainPage.xaml,如代码如下:



 
 
 
 
 

第二步:

打开MainPage.xaml.cs并为视图(图面)添加其对应的模型,代码如下(注意要引入Warensoft.EntLib.Common):

public partial class MainPage : ContentPage
 {
 public MainPage()
 {
 InitializeComponent();
 //此处注册ViewModel
 this.BindingContext = new MainPageViewModel();
 }
 }
 public class MainPageViewModel : ViewModelBase
 {
 public override Task ShowCancel(string title, string message)
 {
 throw new NotImplementedException();
 }
 public override Task ShowConfirm(string title, string message)
 {
 throw new NotImplementedException();
 }
 public override void ShowMessage(string message)
 {
 Application.Current.MainPage.DisplayAlert("提示",message,"OK");
 }
 protected override void InitBindingProperties()
 {
 }
}

第三步:

定义图像组件的模型,并为图像添加X、Y坐标轴,添加一个K线和一条直线,代码如下所示:

public PlotModel Model
 {
 get { return this.GetProperty("Model"); }
 set { this.SetProperty("Model", value); }
 }
 protected override void InitBindingProperties()
 {
 this.Model = new PlotModel();
 //添加X、Y轴
 this.Model.Axes.Add(new OxyPlot.Axes.DateTimeAxis()
 {
 Position = AxisPosition.Bottom,
 StringFormat = "HH:mm",
 MajorGridlineStyle = LineStyle.Solid,
 IntervalType = DateTimeIntervalType.Minutes,
 IntervalLength = 30,
 MinorIntervalType = DateTimeIntervalType.Minutes,
 Key = "Time",
 });
 this.Model.Axes.Add(new OxyPlot.Axes.LinearAxis()
 {
 Position = AxisPosition.Right,
 MajorGridlineStyle = LineStyle.Solid,
 MinorGridlineStyle = LineStyle.Dot,
 IntervalLength = 30,
 IsPanEnabled = false,
 IsZoomEnabled = false,
 TickStyle = TickStyle.Inside,
 });
 //添加K线和直线
 this.candle = new OxyPlot.Series.CandleStickSeries();
 this.line = new OxyPlot.Series.LineSeries() { Color = OxyColors.Blue };
 this.Model.Series.Add(this.candle);
 this.Model.Series.Add(this.line);
 }

第四步:

添加获取K线函数(以OKCoin为例),代码如下:

/// 
 /// 读取OKCoin的15分钟K线
 /// 
 /// 
 public async Task> LoadKline()
 {
 var url = $"https://www.okcoin.cn/api/v1/kline.do?symbol=btc_cny&type=15min&size=100";
 HttpClient client = new HttpClient();
 var result = await client.GetStringAsync(url);
 dynamic k = Newtonsoft.Json.JsonConvert.DeserializeObject(result);
 List lines = new List();
 int index = 0;
 foreach (var item in k)
 {
 List d = new List();
 foreach (var dd in item)
 {
  d.Add((double)((dynamic)dd).Value);
 }
 lines.Add(new Kline() { Data = d.ToArray()});
 index++;
 }
 return lines;
 }

第五步:

添加定时刷新并绘制图像的函数,代码如下所示:

private StockServiceDriver driver;
 public async Task UpdateData()
 {
 //初始化WarensoftSocketService客户端驱动,此处使用的是测试用AppKey和SecretKey
 this.driver = new StockServiceDriver("C6651783-A3B9-4B72-8B02-A2E67A59C5A6", "6C442B3AF58D4DDA81BB03B353C0D7D8");
 await Task.Run(async()=>
 {
 while (true)
 {
  try
  {
  //读取K线
  var kline =await this.LoadKline();
  //远程Warensoft Stock Service 分析SAR曲线
  var sar = await this.driver.GetSAR(kline);
  //绘图,注意办为需要更新UI,因此需要在主线程中执行更新代码
  this.SafeInvoke(()=> {
  //每次更新前,需要将旧数据清空
  this.candle.Items.Clear();
  this.line.Points.Clear();
  foreach (var item in kline.OrderBy(k=>k.Time))
  {
  //注意将时间改为OxyPlot能识别的格式
  var time = OxyPlot.Axes.DateTimeAxis.ToDouble(item.Time);
  this.candle.Items.Add(new HighLowItem(time,item.High,item.Low,item.Open,item.Close));
  }
  if (sar.OperationDone)
  {
  foreach (var item in sar.AdditionalData.OrderBy(s=>s.DateTime))
  {
   var time= OxyPlot.Axes.DateTimeAxis.ToDouble(item.DateTime);
 this.line.Points.Add(new DataPoint(time, item.Value));
  }
  }
  //更新UI
  this.Model.InvalidatePlot(true);
  });
  }
  catch (Exception ex)
  {
  }
  await Task.Delay(5000);
 }
 });
 }
