本教程的目标是快速介绍PyAlgoTrade。PyAlgoTrade的目标是帮助您实现股票交易策略。假设您有一个交易策略的想法，并且您希望使用历史数据进行评估，并查看其行为方式，那么PyAlgoTrade应该允许您以最小的努力来做到这一点。
本教程是在UNIX环境中开发的，但将其适应Windows环境的步骤应该很简单。
PyAlgoTrade有6个主要组件：
- 策略（Strategies）
- 数据集（Feeds）
- 券商（Brokers）
- DataSeries
- 技术指标
- 优化
策略
这些是您定义的实现交易逻辑的类。何时购买，何时出售等
数据集
这些是提供抽象的数据。例如，您将使用CSV提要，从CSV（逗号分隔值）格式化的文件中加载条来将数据提供给策略。饲料不限于酒吧。例如，有一个Twitter Feed可以将Twitter事件纳入交易决策。
券商
经纪人负责执行订单。
DataSeries
数据系列是用于管理时间序列数据的抽象。
技术指标
这些是用于在DataSeries之上进行计算的一组过滤器。例如SMA（简单移动平均），RSI（相对强度指数）等。这些过滤器被建模为DataSeries装饰器。
优化
这些是一组允许您在不同计算机或在同一台计算机中运行的不同进程之间进行回测的方法，或两者的组合。它们使水平缩放变得容易。
说完这一切，我们需要测试我们的策略的第一件事是一些数据。让我们使用Oracle 2000年的股票价格，我们将使用以下命令下载：
from pyalgotrade.tools import yahoofinance;
yahoofinance.download_daily_bars('orcl',2000,'orcl-2000.csv')
dw = pd.read_csv("orcl-2000.csv")
dw
