An Overview,eraged both in industry and academia. I cover the use of the R programming language, as well as the R environment as a means for manipulating financial market data and for solving a subset of problems that quants and traders typically encounter in their day-to-day activities. The chapters that follo

Basic Statistics and Probability,basic visualizations with ggplot2. The next logical step is to start looking for patterns in the data that might reveal exploitable trading opportunities. This course of action inevitably leads us to ask questions about the statistical nature of financial time series.

Spreads, Betas and Risk, day’s return does not help us in forecasting today’s return. The hypothesis we will formulate in this section is that we can artificially create a time series that is somewhat forecastable. We will refer to this new time series as a spread. The claim we are making is that a stock spread has a bette

Backtesting with Quantstrat,hodology of testing out a particular hypothesis about market dynamics on a subset of historical data. It is akin to the scientific method in that it attempts to reconcile hypotheses with empirical observations. The end goal is to form predictions that result in profitable outcomes. The implicit assu

High-Frequency Data,ously spaced out in time. Homogeneity in time is a property that makes the mathematics of time series analysis much easier to handle. Tick data, on the other hand, is inherently nonhomogenous in time. Events such as book updates, trade updates, exchange messages and high-frequency news feeds, tend t
