Optional: your own spread, commission and contract size

Broker cost comparison
Same conditions for every broker: symbol, lots, price, leverage and currency come from the trading calculator above. Choose the account type below.
Not a ranking, and no broker is claimed to be cheapest. Contract specifications can differ between brokers; until broker-specific specs are configured, the same reference spec is used for all, so margin is identical. Spreads change with the market; "No data" means no figure is available.
Rebate calculator
Estimated rebate you receive under the configured rule. A broker's own commission is not your rebate, and it is shown separately.
Position size and risk calculator
Works out a reference lot size so that a stop-loss hit loses about the risk amount you choose. This is separate from the margin calculation.
Slippage, spread widening and market gaps can make the real loss higher than this estimate. This is not advice; the stop-loss is not guaranteed to fill at your price.
Contract size, minimum price step and lot limits are general industry reference values, not confirmed with this broker. Edit contract size below if your account differs.

FAQ, data sources, risk and privacy
What is an IB rebate?
An Introducing Broker (IB) refers clients to a broker and may receive a commission. Part of that can be shared with clients as a rebate on their trades.
Spread cost vs rebate: what is the difference?
Spread cost is what you pay through the bid-ask spread when you trade. The rebate is a partial refund per lot. They are shown separately.
How is net cost calculated?
Net cost = spread cost - rebate. Choose a broker and enter your lots in the calculator to see an estimate.
Data sources: broker facts come from WikiFX (third party, checked 2026-10-28) and each broker's public pages. Spreads are not live: no official quote feed is connected, and any spread shown is labelled as a reference or your own input. Rebate figures are supplied by the site operator.
