Market sentiment dashboard using Curl and PHP

In this article I will show you how to create a little Dashboard of  Market Sentiment results taken on differents IG Trading web-pages. And feed it in a HTML table for Dashboard.

The use of Curl in PHP will permit you to create Dashboard of data from different Websites, in the same page.

DEMO: See it in action: http://www.pc-dream.it/curl.php

Warning: Don't use the following script for Trading! 

Firtly I would like to "read" the market sentiment on IG symbols webpages like the following:

https://www.ig.com/it/indici/mercati-indici/germany-30

Then I need to scrap from each page two informations:
- Percentage of customer wich have positions open Short/long
- Direction of the position: Short or Long

1. To do so I will use Curl function of PHP. The following script will extract all text of 'ma__title' class, then the symbol name of Index or currency...
2. You also need to copy and integrate dom parser functions to "read" the html page and extract some text: you can download here: http://simplehtmldom.sourceforge.net/ but you just need to include the following file: simple_html_dom.php in your code.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url[$x]);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch);
curl_close($ch);

$html = new simple_html_dom();
$html->load($response);

echo "  <tr>";
echo "<td class='tg-us36'>";
foreach($html->find('.ma__title') as $symbol)
echo "<a href='$url[$x]' target='_blank'>". $symbol->plaintext ."</a>";
echo "</td>";

$symbol=$symbol->plaintext;

Each url you provide in $url[$x] array will be read and the results will be append in  HTML in a FOR LOOP

At each row, you can calculate an action depending of the market sentiment, i.e. if you would like to BUY each time Sentiment percentage is above 70% you can add the following scritp:

foreach($html->find('.information-popup strong') as $result) {
if ($precent<71) {echo 'CLOSE';}
else{
if ($result->plaintext == 'ha posizioni short') echo '<b>SELL</b>';
if ($result->plaintext == 'ha posizioni long') echo '<b>BUY</b>';
}
}

Notice that you can create trading bots in TagUI which can go to your PHP dashboard and read the "Action" and schedule it each hour or 30' ...
