Found this article about Regulated BO Brokers - http://www.binaryex.com/regulated-binary-options/
I might be misunderstanding binaries, if so disregard the following. Why not just trade vertical spreads with a normal broker?
i'm looking at opteck, optionbit, optionsxo, and regal options. This is out of a list of 40 brokers (and growing) which take US customers, have range and no touches etc.
Any dealer willing to take US clients is going to rip you off. Those dealers are shit and only allow you to go long digitals and touches.
