An open and transparent process that aims to create a single price for halt resumptions (resumption of trading after a halt) based on supply and demand. The process determines the price at which eligible interest shall be executed at the resumption of trading for a halted security. A halt cross occurs in many situations including when the initial price of a security is closest to the lowest price of the price range disclosed by an issuer in its effective registration statement, or when the initial price of a security, that traded in the over-the-counter market immediately prior to the initial pricing, is closest to the most recent transaction price in that market.

A halt cross may also be triggered in the case of another halt type in which the security has already traded during normal market hours on that trading day, and the price is closest to the last execution level prior to the trading halt, or when another type of halt occurs such as a halt where the security has not already traded during normal market hours on that trading day, and the price is closest to the previous official closing price.
