Tai - Orchestrate Your Trading

A composable, real time, market data and trade execution toolkit. Built with Elixir, runs on the Erlang virtual machine

What Can I Do? TLDR;

Stream market data to create and manage orders with a near-uniform API across multiple venues

Here's an example of an advisor that logs the spread between multiple products on multiple venues

Install

tai requires Elixir 1.11+ & Erlang/OTP 22+. Add tai to your list of dependencies in mix.exs

def deps do
  [
    {:tai, "~> 0.0.75"}
    # Choose your order data store
    # {:ecto_sqlite3, "~> 0.5.6"}
    # {:postgrex, "~> 0.15"}
  ]
end

Create an .iex.exs file in the root of your project and import the tai helper

# .iex.exs
Application.put_env(:elixir, :ansi_enabled, true)

import Tai.IEx

Run the setup mix task to:

Download dependencies
Create an orders database
Generate tai migrations for the orders database
Run migrations

$ mix setup

Usage

tai runs as an OTP application.

During development we can leverage mix to compile and run our application with an interactive Elixir shell that imports the set of tai helper commands.

iex -S mix

Upgrading Tai

Bump the required version number in mix.exs and download the dependencies.

$ mix deps.update tai

Regenerate new or updated migrations

$ mix tai.gen.migration

Rerun ecto migrations

$ mix ecto.migrate

Help Wanted :)

If you think this tai thing might be worthwhile and you don't see a feature or venue listed we would love your contributions to add them! Feel free to drop us an email or open a Github issue.
