分析Cointrader有一定层度了，发现它毕竟不是一个产品，没有得到验证。在架构、编码等方面都非常的不规范。

想编写一个云交易平台，任道而重远。我们需要参照一些成熟的架构。

Quantopian的zipline不行，因为我就是看到它不行，所以才去分析Cointrader的。

现在这两个，一个压根就不是云平台，一个是不成熟，所以我只能去分析剩下的一个QuantConnect了。它的引擎是lean。

学习lean从学习使用开始，然后学习其架构、源码。然后设计我们的架构、平台。

我们首先来看一个例子。官方的最基本的案例。

代码如下：

namespace QuantConnect {       /*    *   QuantConnect University: Full Basic Template:    *    *   The underlying QCAlgorithm class is full of helper methods which enable you to use QuantConnect.    *   We have explained some of these here, but the full algorithm can be found at:    *   https://github.com/QuantConnect/QCAlgorithm/blob/master/QuantConnect.Algorithm/QCAlgorithm.cs    */    public class BasicTemplateAlgorithm : QCAlgorithm    {        //Initialize the data and resolution you require for your strategy

        public override void Initialize()        {            //Start and End Date range for the backtest:            SetStartDate(2013, 1, 1);                     SetEndDate(DateTime.Now.Date.AddDays(-1));                         //Cash allocation            SetCash(25000);                        //Add as many securities as you like. All the data will be passed into the event handler:            AddSecurity(SecurityType.Equity, "SPY", Resolution.Minute);        }        //Data Event Handler: New data arrives here. "TradeBars" type is a dictionary of strings so you can access it by symbol.        public void OnData(TradeBars data)         {               // "TradeBars" object holds many "TradeBar" objects: it is a dictionary indexed by the symbol:            //             //  e.g.  data["MSFT"] data["GOOG"]                        if (!Portfolio.HoldStock)             {                int quantity = (int)Math.Floor(Portfolio.Cash / data["SPY"].Close);                                //Order function places trades: enter the string symbol and the quantity you want:                Order("SPY",  quantity);                                //Debug sends messages to the user console: "Time" is the algorithm time keeper object                 Debug("Purchased SPY on " + Time.ToShortDateString());                                //You can also use log to send longer messages to a file. You are capped to 10kb                //Log("This is a longer message send to log.");            }        }    }}
