Settlement fees are currently set at 0.00; however this is subject to change.
Quoting surcharge determined at end of day for customers whose order/trade ratio exceeds 5:1. Only new orders and modifications but not order cancels will count in the ratio. For example: 4 orders, each modified once, resulting in 1 execution total -> charge of EUR 6 (3*2 EUR).
IB calculates external fees based on trade value. Trade value is defined as Nominal*PriceInPercent/100.
