What is the spread?
The spread is the difference between the buy and sell price. It can change with market conditions. A figure such as “from” therefore does not automatically describe the spread you get on every trade.
For a useful cost comparison, market, trading time and position size should match. Simply comparing two minimum spread figures is not enough.
What is the commission?
A commission is a separately stated trading fee. Depending on broker and account model, a tighter spread can come with an additional commission. Other models charge the broker’s payment via a mark-up in the spread.
Check whether a stated commission applies to one side of the trade or to opening and closing together. Without this information, two seemingly equal prices can cost different amounts.
How to compare after cashback
First determine the trading costs on the same basis. Deduct from this only the rebate you can actually expect and are entitled to. If further costs apply, they belong in your comparison too.
A simplified calculation example: with assumed costs of 10 and a rebate of 2, 8 remain in the same currency. This is purely an illustration, not a DualNet rate and not a broker offer.
What the DualNet calculator shows
The calculator is for viewing the cashback conditions stored at DualNet for broker, account type and market. It does not replace a complete cost statement from your broker.
If a rate or market cannot be selected, no other rate can be derived from it. Clarify the conditions for the specific account before you calculate with an amount.
