NAME
PDL::Finance::TA - Technical Analysis Library (http://ta-lib.org) bindings for PDL
SYNOPSIS
use PDL;
use PDL::Finance::TA;
# first load market data you want to analyze
my $open = ... ; # 1D piddle
my $high = ... ; # 1D piddle
my $low = ... ; # 1D piddle
my $close = ... ; # 1D piddle
my $volume = ... ; # 1D piddle
my $period = 20;
my $moving_average = ta_sma($close, $period);
my $money_flow_index = ta_mfi($high, $low, $close, $volume, $period);
# both $moving_average and $money_flow_index are 1D piddlesDESCRIPTION
TA-Lib library - http://ta-lib.org - is a multi-platform tool for market analysis. TA-Lib is widely used by trading software developers requiring to perform technical analysis of financial market data.
This module provides an PDL interface for TA-Lib library. It combines rich TA-Lib functionality with excellent PDL performance of handling huge data.
If you are not a PDL user you might be interested in Finance::TA module which provides approximately the same set of functions working with common perl data structures (which is fine if you are not about to process large data sets and if you generally do not worry about performace).

HANDLING BAD VALUES
Most of the available functions may return BAD values, for example:

use PDL::Finance::TA;
my $PD = pdl([0, 1, 2, 3, 4, 5]);
my $MA = ta_ma($PD, 3, 1);
print $MA; # prints: [BAD BAD 1 2 3 4]All available functions handles BAD values in input piddles (BAD values at the beginning are skipped), for example:
use PDL;
use PDL::Finance::TA;
my $PD = pdl([0, 1, 2, 3, 4, 5]);
my $MA1 = ta_ma($PD, 3, 1);
say $MA1; # prints: [BAD BAD 1 2 3 4]
my $MA2 = ta_ma($MA1, 3, 1);
say $MA2; # prints: [BAD BAD BAD BAD 2 3]FUNCTIONS
