Hello, I've recently created an euro based account at IB and I would like to know how cash currency conversions are calculated. I mainly trade US futures although I will soon trade euro futures. Do I pay the EURUSD B/A spread on each conversion? which spread? how many ticks? How is it calculated? I make about 10 trades per day on US futures and it can affect my long term PÂ§L. Thanks for the help, I'm clueless about this question.
