Only closed trades are counted – If your calculation included open or pending trades, these are not eligible for commission/rebate payout. Non-tradable transactions are excluded from rebate calculations.
Trade eligibility rules not met – A trade may be excluded if:
Tiered IB Structure – If you are part of a multi-level IB system (Master IB → Sub-IB → Client), your payout might be a share of the total rebate, not the full amount.
Example:
Broker pays $10 per lot total. (Reference only*)
Master IB keeps $6, Sub-IB gets $4.
If you’re the Sub-IB, you only get the $4 — even if you calculated based on $10.
Currency conversion differences – Exchange rate fluctuations between your trading account currency and the IB commission account currency may slightly affect the final payout amount. This is because the withdrawal process uses the real-time conversion rate at the moment of processing.
Different Product Commission Rates – Rebate rates can differ between instruments
Example:
XAUUSD may pay $7/lot, EURUSD $5/lot, Indices $2/lot. (Reference only*)
If you calculated using one fixed rate, your total estimate may be higher than the actual mixed rate payout.
