# DESCRIPTION
TA-Lib library - [http://ta-lib.org](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](https://metacpan.org/pod/PDL) interface for TA-Lib library. It combines rich TA-Lib functionality with excellent
[PDL](https://metacpan.org/pod/PDL) performance of handling huge data.
If you are not a [PDL](https://metacpan.org/pod/PDL) user you might be interested in [Finance::TA](https://metacpan.org/pod/Finance%3A%3ATA) 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).

Most of the available functions may return BAD values, for example:
use PDL;
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]
