Custom Code Examples

The examples in this document intend to demonstrate how you can send signals to TradersPost from custom programming languages like PHP, Python, etc.

Custom Code

In addition to sending webhooks from third parties, you can send webhooks to TradersPost from custom code using programming languages like PHP or Python. Here is an example using PHP and the Symfony HTTP Client.

This example uses PHP and the Composer package manager. First create a new directory to work inside of.

mkdir traderspost
cd traderspost

Now require the symfony/http-client package using composer.

composer require symfony/http-client

Now you are ready to create a file named traderspost-test.php and paste the following code inside of the file.

<?php
// traderspost-test.php

require 'vendor/autoload.php';

use Symfony\Component\HttpClient\HttpClient;

$webhookUrl = 'https://traderspost.io/trading/webhook/9d9f8620-d60d-416e-827e-0ec01ef93532/9b5b8c4264421f5515fd4fcb6571af50';

$client = HttpClient::create();

$response = $client->request('POST', $webhookUrl, [
    'json' => [
        'ticker' => 'AMD',
        'action' => 'buy',
        'price' => 85.50,
    ]
]);

echo $response->getContent();

Now you are ready to send the webhook to TradersPost!

php traderspost-test.php
{"success":true,"id":"cd481b19-9bb7-4845-8227-523203971d47","payload":{"ticker":"AMD","action":"buy","price":85.50}}

This is a simple example, but you can combine this with a service like Polygon.io to get live real-time market data and build your own completely custom trading strategies and TradersPost can handle the integrations with your broker.

$client = HttpClient::create();

$response = $client->request('POST', $webhookUrl, [
    'json' => [
        'ticker' => 'AMD',

echo $response->getContent();

Python

    json={"ticker": "AMD", "action": "buy", "price": 85.50}

print(r.json())

Ruby

require 'net/http'
require 'uri'
require 'json'

uri = URI.parse('https://webhooks.traderspost.io/trading/webhook/8c9d9620-c50d-416e-926e-0ec01ee83522/a353c3e16f9e3ded7c58cfedd2c38d74')

header = {'Content-Type': 'text/json'}

signal = {
   ticker: 'AMD',
   action: 'buy',
   price: 85.50
}

http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri, header)
request.body = signal.to_json

response = http.request(request)

puts response.body
