Reimplementation of the basic functions of ib-ruby
Try the V10 branch (V 10.19)
- Completed Zeitwerk integration.
- Submitting of orders is still pending. (Aprl 2024)
Documentation: https://ib-ruby.github.io/ib-doc/ (work in progress)
ib-ruby offers a modular access to the TWS-API-Interface of Interactive Brokers.
ib-api provides a simple interface to low-level TWS API-calls.
Install in the usual way
$ gem install ib-api
In its plain vanilla usage, it just exchanges messages with the TWS. Any response is stored in the recieved-Array.
It needs just a few lines of code to place an order
require 'ib-api'
# connect with default parameters
ib = IB::Connection.new
# define a contract to deal with
the_stock = IB::Stock.new symbol: 'TAP'
# order 100 shares for 35 $
limit_order = IB::Order.new limit_price: 35, order_type: 'LMT', total_quantity: 100, action: :buy
ib.send_message :PlaceOrder,
:order => limit_order,
:contract => the_stock,
:local_id => ib.next_local_id
# wait until the orderstate message returned
ib.wait_for :OrderStatus
# print the Orderstatus
puts ib.recieved[:OrderStatus].to_human
# => ["<OrderState: Submitted #17/1528367295 from 2000 filled 0.0/100.0 at 0.0/0.0 why_held >"]Besides storing any TWS-response in an array, callbacks are implemented.
The user subscribes to a certain response and defines the actions in a typically ruby manner. These actions can be defined globaly
ib = IB::Connection.new do |tws|
# Subscribe to TWS alerts/errors and order-related messages
tws.subscribe(:Alert, :OpenOrder, :OrderStatus, :OpenOrderEnd) { |msg| puts msg.to_human }
endor occationally
# first define actions
q = Queue.new # Initialize as Queue
request_id = nil # declare variable
a = ib.subscribe(:Alert, :ContractData, :ContractDataEnd ) do |msg|
case msg
when Messages::Incoming::Alert
q.close if msg.code == 200 # No security found
when Messages::Incoming::ContractData # security returned
q.push msg.contract if msg.request_id == request_id
when Messages::Incoming::ContractDataEnd
q.close if msg.request_id == request_id
end # case
end
# perform request
request_id = ib.send_message :RequestContractData, :contract => Stock.new(symbol: 'T')
while contract = q.pop
puts contract.as_table
end

ib-api is tested via the stable IB-Gateway (Version 10.12) and should work with any current tws-installation.
are invoked by
bundle exec guard
# or
bundle exec rake spec
Integration tests on order-placements are not included. To run the test suite its thus safe to use a real Account.
You have to edit spec/spec.yml and replace the :account-Setting with your own AccountID, even if you connect to a single account.
