Yes, you can. If you have a standard and a large trade bundle at the same time, trades under 250’000 $/€/Fr will be deducted from your standard trade bundle, and trades 250’000 $/€/Fr and larger will be deducted from your large trade bundle.
You will be charged standard commissions when settling your trades, but will be refunded at the end of each month to account for the lower cost of trading with your bundles.
