No. Whether you’ve opened the account directly with the broker or through a rebate service, trading conditions (swaps, spreads and commissions or any other associated fees) must remain the same (if not, please check with the rebate provider or your broker). This is why it is always beneficial to use a rebate provider when selecting a broker to trade with. Rebates are available with almost every forex broker but each cashback service might support a different list of brokers.
