Hi Ronen,
You should use the V5.1 robots. You should install them on a demo account. If you are using MT4 terminal and you see a smiley fact in the upper right had corner of the chart then the robots are installed properly. Now all you need to do is to give them time, maybe even several days, before you may see active trades. Also, you should just let the robots trade 24 hours a day.
Alan,
