# both $moving_average and $money_flow_index are 1D piddles
DESCRIPTION
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 excelent 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;
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]
