In this book we use the quantstrat library version 0.9.1739. quantstrat provides the base functions we will use to build our strategies; adding indicators, signals and creating the rules of when to buy and when to sell. quantstrat is for signal-based trading strategies, not time-based. However, you can create functions that add signals based on time frames and implement those functions as indicators.
quantstrat provides a generic infrastructure to model and backtest signal-based quantitative strategies. It is a high-level abstraction layer (built on xts, FinancialInstrument, blotter, etc.) that allows you to build and test strategies in very few lines of code. quantstrat is still under heavy development but is being used every day on real portfolios.
This is a quantstrat specific initialization. You can check the parameters of initOrders function using the args (initOrders) command. initOrders (portfolio = portfolioName, symbols = symbolstring, initDate = initDate) You can check that the order book is initialized successfully using the get.orderbook (portfolioName) command.

These links must be preserved during merge - and my initial approaches lost all those links. QPDF to the rescue: qpdf book.pdf --pages cover.pdf 1 book.pdf 1-z -- result.pdf. It took me a while to figure out the exact syntax - and wrote this post so I (and other lost book-writing soules) can find it later.
The logic is simple. The algorithm calculates the daily Z-score for every pair of stocks. The Z-score is the number of standard deviations that the pair ratio has diverged from its mean: Z = (R - μ) / σ Where R is the price ratio of both stocks, μ is the mean of the ratio and σ is the standard deviation of the price ratio.
Backgorund. The quantstrat package is built on the blotter package which was developed in 2008. It works best with time series xts objects which can be easily collected using the quantmod package. The blotter package is the accounting package behind the quantstrat system, it can support multiple accounts or multiple portfolios and computes the P&L of trading systems.
