PSEI

This gem fetches the end-of-day values of the Philippine Stock Exchange (PSE). More details available at their website www.pse.com.ph.

Installation

Add this line to your application's Gemfile:

gem 'psei'

And then execute:

$ bundle

Or install it yourself as:

$ gem install psei

Usage

There are two main components in this library, the Security module and the Index module.

Psei::Security

This module is used to get the end-of-day values of all securities in the PSE. The main identifier of these securities are their symbols or tickers. For example, the Philippine Long Distance Telephone Company is defined by their symbol TEL.

First, we need to initialize the module:

@sec = Psei::Security.new

To get the list of all symbols available:

@sec.symbols

This returns an array of all symbols (as strings), sorted by alphabetical order.

To get the values of a specific security:

@sec.value('TEL')

This returns a Hash containing the following information:

• symbol (String) - The security symbol
• alias (String) - The company identifier
• total_volume (Float) - Total number of traded volume of the day
• updown (String) - Identifies if the security has gone up or down in value
• percent_change (Float) - Percentage that the security has changed
• last_price (Float) - The last traded price of the security

To get the values of all securities in a single call:

@sec.values

This returns an array of Hashes, each containing the same information when getting the values of a single security.

Note that these values are only applicable to a specific trading day. To get the date of these values:

@sec.date

Psei::Index

This module is used to get the end-of-day values of all indices in the PSE. This includes the main index (PSEi), as well as industry-specific indices (Financial, Holdings, Mining, Services, etc).

First, we need to initialize the module:

@ind = Psei::Index.new

To get the list of all symbols available:

@ind.symbols

This returns an array of all symbols (as strings).

To get the values of a specific index:

@ind.value('PSE')

This returns a Hash containing the following information:

• symbol (String) - The index symbol
• alias (String) - The index identifier
• total_volume (Float) - Total number of traded volume of the day
• updown (String) - Identifies if the index has gone up or down in value
• percent_change (Float) - Percentage that the index has changed
• last_price (Float) - The last traded price of the index

To get the values of all indices in a single call:

@ind.values

This returns an array of Hashes, each containing the same information when getting the values of a single index.

Note that these values are only applicable to a specific trading day. To get the date of these values:

@ind.date
