pq_addti creates technical indicators on provided datasets use TTR package.

Usage

pq_addti(dt, ...)

Arguments

dt

a list/dataframe of time series datasets.

...

list of technical indicator parameters: sma = list(n=50), macd = list().

1. There are four types of parameters.

   • set by default and do not required, such as 'OHLC', 'HLC', 'HL' and 'volume'.

   • set by default and can be modified, such as 'price', 'prices', 'x'. Its default value is 'close' or 'value' column.

   • always required, such as 'y', 'w'.

   • numeric parameters, such as 'n', 'sd', 'v', 'nFast', 'nSlow', 'nSig', 'accel'. These parameters should be provided, otherwise using default values in corresponding function.

2. TTR functions are summarized in below. See TTR package's help document for more detailed parameters.
