Market opening and closing times aren’t set by TradeLocker. They’re defined by your broker/prop firm and their liquidity provider, and they can differ by symbol and server.
Expect temporary shifts around Daylight Saving Time changes (US/EU) or on holidays such as exchange or national holidays, brokers often adjust session times then.
For exact hours on your account, check your broker/prop firm’s instrument schedule (sometimes called “symbol specifications” or “contract details”) or ask their support for: symbol trading hours, maintenance windows, time zone used on your server, and holiday calendar.
TradeLocker will mirror whatever your broker configures.
