I tring change element in form with price but don't work and I was using special price and fucntion applyRuleToProduct(); but in wasn't good. because special price is for time or for product.

I found solution to this. I created extra table with my new price product and insert this after click "Add to cart" button. Next step in Product.php in methihod priceCalculation().

after 

// Customization price
if ((int) $id_customization) {
	$price += Tools::convertPrice(Customization::getCustomizationPrice($id_customization), $id_currency);
}

I insert my code with get currently price my product.

$price = Db::getInstance()->getValue('SELECT price FROM `' . _DB_PREFIX_ . 'my_new_prod_price` WHERE `user_id`='.$user_id.' OR `user_id`='.Context::getContext()->cookie->id_guest.' AND `product_id`='.$id_product.' AND `cart_id`='.$id_cart.';');
