DaiMon
DaiMon, or more formally DaiMon of the Ferengi, was a command rank used by the Ferengi Alliance.

Terminology 
In the Ferengi language, DaiMon translated to ""; the position was also the equivalent that of a captain. (; ; )
 
It was observed, on occasion, that DaiMons in command of a starship were referred to as "Leader" by members of their crew. () 

In 2366, Betazoid Ambassador Lwaxana Troi, angrily referred to an unwanted Ferengi pursuer as "Demon Tog, or whatever you call yourself." ()

Duties 

DaiMons were authorized to explore new trade opportunities on behalf of the Alliance, and were often empowered to speak on behalf of the Alliance in such matters. () Their duties included reporting to the Ferengi Council. ()

According to another DaiMon, the reason why he was DaiMon of his ship was because he "[took] charge of every situation." ()

The primary agenda of the DaiMon was to earn a profit. () In fact, according to Doctor Farek, "a true DaiMon would not be blinded by lust," during their pursuit of profit. () 

A DaiMon also had the ability to declare any captured starship to be "a loss and open to claim according to the Ferengi Salvage Code." ()

According to one Ferengi first officer, "it is not seemly to question one's own DaiMon" without just cause. ()

Stipulations 
DaiMons were, however, held under strict guidelines in maintaining their command post by the Ferengi government, who had the power to assign or strip an officer of their command. 

The simple misdeed of engaging in an unprofitable venture could lead to them being stripped of their command. Revenge was highly frowned upon, and evidence of one being unstable and dangerous, could result in prison time. () 

As could a severe security breach, such as revealing their command codes that would lead to complete access to the ship's computer. ()

In 2366, Federation starship Captain Jean-Luc Picard threatened to report DaiMon Tog for kidnapping a Federation ambassador and two Starfleet officers to his superiors, indicating that those superiors "may question your competency as DaiMon." () 

A non-Alliance affiliated group of privateers, led by an individual who still possessed the rank of DaiMon, were in business for themselves when they captured the  in 2369, hoping to sell it to the Romulans. Upon their failure, and due to their involvement in a criminal activity, their actions were quickly disavowed by the Ferengi government. ()
