stocks-exchange-client

STEX (former Stocks.Exchange) (Node JS API client)

STEX (former Stocks.Exchange) provides all the core exchange functionality, and additional merchant tools available via the HTTP API where all returned messages are in JSON. It's much easier to work with the API by using one of the clients provided by STEX, so while this page describes the API in case you want or need to build your own client, the examples use the Node JS client.

Requirements

• Node.js
• npm (Node.js package manager)

Dependent Libraries

• "crypto-js": "^3.1.9-1",
• "fs": "0.0.1-security",
• "http-build-query": "^0.7.0",
• "jsonfile": "^5.0.0",
• "pkg": "^4.3.3",
• "request": "^2.87.0"

General

The base URL for all the requests other than public methods is

https://api3.stex.com

Getting started

• Sandbox API

To get started with the Node JS API client, here's a snippet for creating a client with existing credentials:

In order to use the API functions, you must have an API key and API secret, which is generated in the user profile.

Usage

npm install stocks-exchange-client --save

After install use for example this code!

Example WebSocket API

const StocksExchange = require('stocks-exchange-client').client;
const option = {
    client: {
        id: '',
        secret: ''
    },
    tokenObject: {
        'access_token': '',
        'refresh_token': '',
    },
    accessTokenUrl: 'https://api3.stex.com/oauth/token',
    scope: 'trade profile reports withdrawal',
};
const se = new StocksExchange(option, null);
se.subscribeOrderFillCreated(702,function (res) {
    console.log('subscribeOrderFillCreated', res);
});

se.subscribeGlassTotalChanged(702, 'buy', function (res) {
    console.log('subscribeGlassTotalChanged', res);
});

se.subscribeGlassRowChanged(702, 'sell', function (res) {
    console.log('subscribeGlassRowChanged', res);

    console.log('subscribeCandleChanged', res);
});

se.subscribeBalanceChanged(1, function (res) {
    console.log('subscribeBalanceChanged', res);
});

se.subscribeUserOrder(0, 702, 'sell', function (res) {
    console.log('subscribeUserOrder', res);
});

se.subscribeUserOrderDeleted(0, 702, function (res) {
    console.log('subscribeUserOrderDeleted', res);
});

se.subscribeUserOrderFillCreated(0, 702, function (res) {
    console.log('subscribeUserOrderFillCreated', res);
});
