In MetaTrader 4, trailing stops only remain active as long as you’re logged in to the platform.

If you set a trailing stop and then log out of MetaTrader before the market moves in your favour by the number of points that you specified, the trailing stop loss order will not be placed.

In order for your “trailing stop” to be functioned correctly, you have two options:

1. Keep the MT4 opened and logged in at all times or
2. Use the VPS(virtual private network) server and run your MT4 somewhere else constantly

Also cTrader, the ECN trading platform has got “trailing stop” option which you can set in the trading server.

Meaning that with the cTrader, your “trailing stop” order is functional even if you log out and close the platform itself.

FxPro offers MT4 and cTrader, and you can open several accounts to try both of them.
