Traders and shoppers turned up to Plaza Malls, in High Street, Dudley, to find the doors locked on Thursday.
Notices were pasted up on the windows signalling a possession by the landlord Tryst Enterprises Ltd.
On Friday, the market remained closed while negotiations took place between owner Tony Swannie and the landlord.
But the doors reopened just after 3pm and traders retook to their stalls for business to return as usual. Mr Swannie said: "We had a small dispute with the landlord over a discrepancy in payments. Everything is sorted now.
"We are very grateful to be back open and pleased to be busy with shoppers again."
A spokesman for solicitors Cree Godfrey and Wood Solicitors, which represent the landlord, said: "The store should now be back open. The monies have been paid."
Trader Basra Singh runs a ladies fashion store in the market. He said: "It is frustrating. I have lost money from this."
The market houses 46 small shops and stalls over a space of 30,000 sq ft.
