IB commission
IB commission is the fee share an exchange pays to an introducing broker for its referred clients' trading. It is the pool from which trader paybacks are funded under the IB model.
When an introduced client trades, the exchange calculates commission on the fees generated and credits it to the IB under their agreement — usually continuously or in daily batches, proportional to actual fee flow. No client trading, no commission; the IB's income is strictly a function of its clients' real activity.
For traders, the useful insight is directional: your fees create the commission, so any payback you receive is your own money making a round trip through the partnership. The rebate can never exceed the commission, which anchors what honest offers look like.
Platforms differ in how much of the commission they pass on and how transparently they say so. loweef's public numbers are the trader-side totals (50–67% of fees per partner, verification-dated); commission terms with exchanges are contractual and not disclosed, which is standard practice across the industry — the figure that affects you, the share of your fees returned, is the one printed on every page.
