For me Yes, especially those who don't have a plenty of time to watch and waut trading from time to time .just set at that amount so it is waitin to sold or bought .but it is much better if manually.
Many guys i've talked to who tried to trade finally had got their amount less from the beginning value no matter how hard and for how long did they learn. I think in that case the trading robot that will not bring you losses is better than non-profitable manual trading. Does anyone heard about Spy-FX trading robot? It offers a quite big percent.
