If you want to control product quantity after order was placed you have to override classes/stock/StockAvailable::updateQuantity

$product_quantity = StockAvailable::getQuantityAvailableByProduct($id_product);

if( ($product_quantity+$delta_quantity)>=0){

$stockManager = Adapter_ServiceLocator::get('Core_Business_Stock_StockManager');
$stockManager->updateQuantity($product, $id_product_attribute, $delta_quantity, $id_shop = null);
}
