What is the best way to handle this issue? Is it to store the stock$Volume as a temporary object where NA values are removed and then calculate the rolling volume and the merge it back in with merge.xts while adding the fill = NA so NA values are inserted again? But is that correct since you take the last 20 trading days and not just the 19 available in the 20-day window?

functions in TTR cannot handle NAs if they are preceded by numbers and followed by numbers. This is an introductory textbook that focuses on how to use R to do technical analysis.

Before you can look up individual daily stock prices to build your trading algorithm, you need to collect all available stocker tickers. Package ‘TSstudio’ OctoType Package Title Functions for Time Series Analysis and Forecasting Version 0.1. character.only a logical indicating whether package or help can be assumed to be character strings. Non-existent library trees are silently ignored. The default value of NULL corresponds to all libraries currently known to. I have reproduced those days' data below. library (rvest) library (pbapply) library (TTR) library (dygraphs) library (lubridate) Data Collection All the loyal3 stocks are all listed on a single page. a character vector describing the location of R library trees to search through, or NULL. htmlwidgets - A fast way to build interactive (javascript based) visualizations. rgl - Interactive 3D visualizations with R. ggvis - Interactive, web based graphics built with the grammar of graphics. ggplot2 lets you use the grammar of graphics to build layered, customizable plots. I quickly located the problem (which I knew was NA values since I have tried this a 1000 times) and found the two days where volume data is missing. ggplot2 - R's famous package for making beautiful graphics. When I want to calculate rolling 20-day volume the error message occurs: SMA(stock$Volume, 20)Įrror in runSum(x, n) : Series contains non-leading NAs Description The Jensen's alpha is the intercept of the regression equation in the Capital Asset Pricing Model and is in effect the exess return adjusted for systematic risk. functions in TTR cannot handle NAs if they are preceded by numbers and followed by numbers. The example below is about a stock with EOD data since stored in a xts object with four columns named "High","Low","Close","Volume". I quickly located the problem (which I knew was NA values since I have tried this a 1000 times) and found the two days where volume data is missing. R-release (arm64): TTR_0.24.3.tgz, r-oldrel (arm64): TTR_0.24.3.tgz, r-release (x86_64): TTR_0.24.3.tgz, r-oldrel (x86_64): TTR_0.24.3.I often run into the same issue of how to handle NA values when modelling quantitative trading models. Once you have read the time series data into R, the next step is to store the data in a time series object in R, so that you can use R’s many functions for analysing time series data. The package also provides fast implementations of common rolling-window functions, and several volatility calculations.
