Answer 1

You need to use foreach twice.

PHP Code:

/* Generating structure */
$rawdata = array(
        '',
        1,
        array(
            array(
                'TradeID' => 15950315,
                'Price' => 0.00000170,
                'Type' => 'buy',
                'Amount' => 712.85989430,
                'Total' => 0.00121368,
                'Time' => 1535337908,
            ),
            array(
                'TradeID' => 15908375,
                'Price' => 0.00000300,
                'Type' => 'buy',
                'Amount' => 574.71264368,
                'Total' => 0.00172673,
                'Time' => 1535022882,
            )
        )
    );
$data = (object)$rawdata;
print_r($data);// same output as shown in the question


/** Getting TradeID */

foreach ($data as $key => $value) {
    if (is_array($value)) {
        foreach ($value as $tradeKey => $tradevalue) {
            echo $tradevalue['TradeID'].'<br/>';
        }
    }
}

Answer 2

Considering the $object variable would be the object you see, and only the first layer is an object, you can cast to an array using the notation (array) and continue the logic that you probably know already:

$array = (array) $object;

foreach ($array['2'] as $item) {
    echo $item['TradeID'];
}

Sorry for the previous answer, this one is fixed and tested here: https://3v4l.org/LOYtp
