RShiny App — av_runShiny • alphavantagepf

av_runShiny() runs an interactive RShiny app with a professional command line interface to download, manage, and visualize data from the Alpha Vantage data service. The app treats equities, ETFs, indices, and FX equally, so users do not need to know specific API calls to integrate data. Downloaded data is cached to reduce API calls, all data can be saved for external use, and both external data and external commands (that call user functions) can be added to the app. Sets of securities can be easily added and managed.

Usage

av_runShiny()

Value

Nothing

A ShinyAppHandle object.

Details

Invocation starts Shiny application. See vignettes for full details. On first use, In the AVOPTS tab, fill in the following fields, and hit the "Set Opts" button.

AV API Key: API key obtained from Alpha Vantage
Entitlement Entitlement status (either delayed or realtime) Other options that can be set are given below.

To get data and run analyses:

Enter in the top yellowed line a semicolon delimited set of securities (Equity, ETF, FX, Crypto, indices) followed by a command to run analytics on those securities. Commands without securities are always prefixed by "AV.". THe results are shown as tables, plots, or dygraphs below the command line, and possibly in an additional tab to the right of the main tab. Some commands may change the focus to specialized tabs (e.g.NEWSorOPTIONS`). Commands are not case sensitive, and may refer to a counterasset in the second yellowed line. A few examples include:

Command	Description
`AV.H`	List all available functions
`AV.INV`	Inventory of all available data
`AV.TICKERS`	Inventory of indices and crypto pairs available from Alpha Vantage
`SPACE S`	Search for all tickers with `SPACE` in their names
`IBM;QQQ;NDX;USD/MXN GPI`	Produce a rebased time series graph of the securities
`IBM;QQQ GV`	Time series graph of rolling volatiliies
`IBM;QQQ GV`	Time series graph of rolling volatiliies
`IBM;AAPL;USD/MXN Q`	Table of latest prices for each instrument
`USD/BRL;USD/MXN SCATI`	Scatterplot of rebased levels and returns
`IBM;AAPL EA`	Table of Earnings data for each instrument
`IBM;AAPL CN`	Table of recent news items for each asset, with links
`IBM;AAPL RV`	Graph of excess returns over counterasset (`SPY` by default)
`IBM OS F,M,P,otm`	Search for (e.g.) Out of the money front month puts

If an analysis requires price, dividend or earnings data that is not in the app's internal store, then it will download it as necessary from Alpha Vantage. Other data (e.g. News, options) are downloaded freshly each time. One of the key contributions of this app is to abstract out the asset-specific functions calls that are necessary to do cross-asset analyses.

Other niceties:

Groups of assets can be named, saved, and recalled easily. See Basic Usage vignette
Internal data can be stored and used (as data.table()s) in a directory of the users' choosing. See setup vignette.
Events and other plotting options can be specified in the app. See functions vignette and e.g. FinanceGraphs
Data within each produced graph or table can be copied to the clipboard (option in AVOPTS page), See setup vignette.
Raw downloaded data can be saved into a "dump directory" (option in AVOPTS page)
A current inventory list is always kept in a separate tab, avoiding having to run AV.INV repeatedly.
User price data, earnings data, and asset groups can be added using helper functions av_add_px(), av_add_earn(), av_add_assetgroups(). See Extensions vignette
User analytics can be added using av_add_analytic(). See examples in the Extensions vignette
