A JavaScript WealthSimple Trade API Wrapper

wstrade-api

A tiny Unofficial WealthSimple Trade API Wrapper for JavaScript, supporting the core abilities of the WealthSimple Trade application including placing orders, viewing and cancelling orders, and more.

Disclaimer

USE AT YOUR OWN RISK. This is an unofficial WealthSimple Trade API Wrapper, and it is new. While i did (to my best ability) test the functions, there is absolutely no guarantee that there are no bugs in the code. The API Wrapper will be improved over time.

DO NOT LEVERAGE THIS IN ATTEMPT TO DISRUPT ORDERLY MARKET FUNCTIONS. This package is provided to you so you can build cool shit with it, but you should understand that you have a responsibility to not engage in illegal trading behaviours that can disrupt orderly market functions. This means that you should not flood the API with orders in a fast manner. You might even get banned or locked out by WealthSimple Trade if you abuse their endpoints.

You would be abusing this tool if you are leveraging it to carry out tactics that would provide you illegitimate personal gains. For example, Spoofing is a forbidden tactic that has demonstrable negative effects on the operation of the markets.

My recommendation is to be very conservative on how many orders you place within a small timeframe. I have no idea what the maximum amount of orders is by any timeframe, but if you have a gut feeling that it is too much, then it is too much.

Getting Started

Before playing with wstrade-api, you must have a valid WealthSimple Trade account to authenticate against. If you have not signed up for WealthSimple Trade, you may download the iOS application here or the android application here.

Prerequisites

You just need node.js — and npm, obviously.

Installing

Install wstrade-api from the npm registry

npm i wstrade-api

You could also clone the GitHub repository

git clone [email protected]:ahmedsakr/wstrade-api.git

Dependencies

The dependency list is tiny — node-fetch and http-status. That's it.

• node-fetch - Used for interacting with the WealthSimple Trade API
• http-status - Used for well-known HTTP status codes.

Documentation

After installing wstrade-api from the npm registry, import it into your JavaScript file.

import trade from 'wstrade-api';

Server-Side Limitation

This wrapper will not work when executed on the client-side due to the underlying CORS security limitation imposed by the WealthSimple Trade endpoints. If you wish to build a front-end application, you will have to design an architecture where the server does all of the API calls.

Failure return

For all API Calls, the failure return is standardized to the following:

{
    status, // HTTP status
    reason, // Failure reason,

    // The body of the response
    body: {
        ...
    } 
}
