tradesCleanupUsingQuotes: Perform a final cleaning procedure on trade data

Description

Function performs cleaning procedure rmTradeOutliersUsingQuotes for the trades of all stocks data in "datadestination". Note that preferably the input data for this function is trade and quote data cleaned by respectively e.g. tradesCleanup and quotesCleanup.

Usage

tradesCleanupUsingQuotes(
  datasource = NULL,
  datadestination = NULL,
  tdata = NULL,
  qdata = NULL
)

Arguments

datasource

character indicating the folder in which the original data is stored.

datadestination

character indicating the folder in which the cleaned data is stored, folder of datasource by default.

tdata

data.table or xts object containing (ONE day and for ONE stock only) trade data cleaned by tradesCleanup. This argument is NULL by default. Enabling it, means the arguments from, to, datasource and datadestination will be ignored. (only advisable for small chunks of data)

qdata

data.table or xts object containing (ONE day and for ONE stock only) cleaned quote data. This argument is NULL by default. Enabling it means the arguments from, to, datasource, datadestination will be ignored. (only advisable for small chunks of data)

Value

For each day an xts object is saved into the folder of that date, containing the cleaned data.

In case you supply the arguments "tdata" and "qdata", the on-disk functionality is ignored and the function returns cleaned trades as a data.table or xts object (see examples).
