App database functions

Description

Adds price data to av_runShiny() internal data.

Usage

av_add_data(indta, assettypes = NULL, delay = 0)

Arguments

indta	A data.frame with the following minimal columns: c(symbol,timestamp,close,adjusted_close). Other variables added could be c(open,high,low,volume,dividend_amount,split_coefficient)
assettypes	(default NULL) An optional data.frame with minimal columns c(symbol,type,currency,name) with descriptive data for the assets given in indta. If not specified, a call to av_get_pf(.,"SYMBOL_SEARCH") is necessary to determine the asset type (one of c("Equity","ETF","FX","Index","Crypto")) for subsequent calls to av_get_pf()
delay	(default 0) Seconds to delay calls to determine asset type for future AV downloads. This is unused if assettypes is given.

Details

Entire set of columns from av_get_pf() can be added. First date column renamed to timestamp
