GT::Analyzers::Process
This module offes all those functions that are needed by the analyzers shell to interactively analyze and test portfolios.
GT::Analyzers::Process->new()GT::Analyzers::Process->parse( $cmd )This function parses the command $cmd. If the shell is set in expert mod it tries first to map $cmd to an internat command and otherwise evaluates it using eval.
GT::Analyzers::Process->bye()Exits the program after asking if the history should be stored.
GT::Analyzers::Process->set( [ $key ] )Set a configuration-parameter. If key is not given, the list of parameters is given. The variable key consits of the real key and the value separated by a space. If you want to set an array, you can either use key[x] to teh xth element or +key to add the value to the array.
GT::Analyzers::Process->set_code( $code )Set the code and do the necessary initialization-stuff.
GT::Analyzers::Process->load( $sys, $dir, $code )Loads $sys from $dir and $code (optional).
GT::Analyzers::Process->save( $sys, $dir )Saves the portfolio with name $sys to directory $dir.
GT::Analyzers::Process->list( $dir )Lists the systems in directory $dir.
GT::Analyzers::Process->btest()start the backtest.
GT::Analyzers::Process->calc($args)Calculates the expression given as argument(s).
GT::Analyzers::Process->calc_array($arg1, $arg2, ...)Calculates each array and prints out/returns a list.
The arry should have the same length.
GT::Analyzers::Process->p($arg)Prints out the string $arg and replaces the variable elements
GT::Analyzers::Process->help()Print the help screen
GT::Analyzers::Process->licence()Print the licence
GT::Analyzers::Process->license()Prints the license
GT::Analyzers::Process->disconnect()Disconnect from database.
GT::Analyzers::Process->info()Prints a small information shown at the start of anashell.
GT::Analyzers::Process->pg_hist()Uncomment this function to plot histograms with pgplot.
GT::Analyzers::Process->r_hist( $array )Plots a histogram using R (www.r-project.org) of the values of $array.
GT::Analyzers::Process->r_bar( $array )Generates a barplot in R by using the values of $array
GT::Analyzers::Process->r_corr( $arr1, $arr2 )Plots the correlation of $arr1 and $arr2 in R.
GT::Analyzers::Process->report( $file )Prints the report of the portfolio using $file as template.
