I recently opened a additional account in IB. While going through the details, I was given a choice of accepting or rejecting "arbitration procedures". That is, in case of a dispute, if I am waiving my rights to a court or not (arbitration finding would be final). Like I said, it was optional - I could take it or leave it. But the terms also said, rejecting "arbitration provision" can result in "reduced trading limits". Any one knows what those "reduced trading limits" are? How it works with other brokers?
