DB::MetaStock access module

Overview

The MetaStock access module is able to retrieve quotes from almost any type of MetaStock/Computrac database.

Note

This module calls the binary program identified by the $HOME/.gt/options file option ``DB::metastock::program'' (``/bourse/tools/MetaStockReader'' by default) to get quotes from your metastock database.

$HOME/.gt/options file option ``DB::metastock::directory'' must indicate the directory of the metastock database. (no default).

Please refer to /bourse/tools/MetaStockReader source if you want to learn more about it.

NOTE: this module and the companion binary program has been depreciated in favor of the stand-alone perl module (unfortunately) also named MetaStockReader. refer to that modules pod
