You can request to turn on your trailing stop-loss option in Metatrader for both Live and Demo accounts.
Trailing stops are enabled by default on MT4 accounts, whereas for MT5 accounts it must be requested to our Support Team. to support@naga.com.
A trailing stop, also called trailing stop-loss, is an order type designed to lock in profits or limit losses as a trade moves favorably. Trailing stops only move if the price moves favorably. Once it moves to lock in a profit or reduce a loss, it does not move back in the other direction.
