Introduction

The weboscket has an emphasis on speed and availability. The code and access is geared towards developers and traders who have a thirst for comparable data points. You could use this repo for example to build algorithms that directly lock into the executium signals marketplace.

Online Example

You can view an online example at the following address: https://marketdata.executium.com/realtime-cryptocurrency-market-prices-websockets/

In addition, we provide a PHP websocket access repository.

CDN

You can access the CDN by including the following:

<script src="https://cdn.executium.com/media/dist/realtime-cryptocurrency-markets/min.js"></script>

The script relies on jQuery, Numerals and Socket.io, for a flawless installation include the following:

<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.3.0/socket.io.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/numeral.js/2.0.6/numeral.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

Running the service

When you want to connect to the server, have the following code example execute.

// Connect to the Public Websocket
socket_connect(wssBASE,'https:\/\/'+wssBASE+':2083','obreq');
// Request Bitfinex BTCUSD
request_orderbook_server('bitfinex', 'btcusd', 'bids');

Make sure you have the classes on page to handle the output.

<div class="bids-bitfinex-btcusd-price">&hellip;</div>
<div class="bids-bitfinex-btcusd-qty">&hellip;</div>
<div class="bids-bitfinex-btcusd-ago ago">&hellip;</div>

Time considerations

You will note in the demo that we put an emphasis on time. We provide tools to promote transparency and a test bed to make sure that you are confident with the results you are getting back. You can find the check time offset extract here.

How the websocket works

Due to the volume of market pairs/symbols we carry across a wide array of exchanges, we have a method of request-location and access-feed to establish the correct websocket in which you should access.

• teller provides direction of where the symbol data resides, you then use this information to connect to the symbol data socket which is currently the base point of wss-socket.executium.com.
• symbol-server this is where you will connect to based on that information the teller provides back. These are subject to change and mvsym will indicate if a new server has taken control as it load balances itself.

It is important to note, that these are always subject to change location, as they are balanced based on an overall network demand. When a symbol is rebalanced to a new location, the mvsym catch provides the mechanism for you to update your location. This code is provided in the example.

Code breakdown

This section will serve as a region to breakdown in detail how the process of connecting to the websockets works.

Subscription for endpoint access

Each domain serving is provided fair-usage terms. We do have additional tiers of subscription for users which use a lot more resource. You can use the executium market prices websocket within fair usage guidelines and if your project is freely available. If you are charging for access or behind any paywall you must purchase a subscription related to that.

User Projects
