Yesterday, Mirus Futures' CEO announced that they are entering an exclusive partnership with Dorman Trading as a Guaranteed Introducing Broker. (See https://ninjatrader.com/)

Upon looking for a definition, I stumbled on this:

An Introducing Broker that has entered into a guarantee agreement with a Futures Commission Merchant, whereby the FCM agrees to be jointly and severally liable for all of the Introducing Broker’s obligations under the Commodity Exchange Act. By entering into the agreement, the Introducing Broker is relieved from the necessity of raising its own capital to satisfy minimum financial requirements. In contrast, an independent Introducing Broker must raise its own capital to meet minimum financial requirements.

Any opinions on why they would drop RCG and RJO, and stick with Dorman overnight?

Justin,

There are already multiple threads on Mirus and on this current situation. Creating a new one just creates a split topic.
