The 22-year-old is the third newcomer in a week after the arrivals of Canada midfielder Terry Dunfield and former Barnsley and Leeds midfielder Martin Woods.
Reckord, who made two appearances for Wolves and had loan spells at Northampton, Coventry, Scunthorpe and Plymouth, has signed until the end of January.
Manager Jim McIntyre said: “He is 6ft 1in, an athletic player, great left foot, quality on the ball, and I think he’ll do very well.”
McIntyre, who also signed Lewis Toshney since arriving after the end of the transfer window, has taken former Motherwell defender Paul Quinn on trial too.
The signing spree comes after Richard Brittain and Rocco Quinn were told they needed operations.
Brittain faces up to four weeks out when he has foot surgery - although he will firstly be available for the visit of Celtic on Saturday - while Quinn is out for several months with a hip problem.
McIntyre said: “We felt it was important to cover the positions with a couple of players needing operations. It adds good players to the ones we already have.”
McIntyre has secured improvement from his side in recent weeks, having beaten Dundee and drawn with Inverness, and wants a similar display against the champions.
“We’ve got to make sure we continue what we have been doing in the last couple of games, first and foremost the hard work they are putting in, the organisation and creating chances, and it’s important we take a higher percentage,” he said.
