I prefer to use a stop loss when the position has achieved a profit, put SL on a green pips because then when we left the floating plus, and we turn off the pc / laptop, then we would not doubt whatever happen it won't be floating minus.
but it would be otherwise if we do the same thing by using a trailing stop, then maybe after we turn off the pc / laptop then turn it on again the next day, if the price changes turns into the opposite direction, then the trading positions that had been profit will be changed to minus . because the trailing stop will work only if your trading terminal always connected to the Internet.
