Jetus,
If you click on the main robot section and scroll down, you will see many reference documents regarding the hows and whys of the robots. These are trade decision systems that are based on a probability analysis of the three days and 10 days risk/rewards statistics. If a edge is found, a signal is provided, with an entry price and a stop level. The stops and signals are updated daily before markets opens. Dual robots subscribers have access to the Pivots discussion group led by Billy.
Since there is a 30 days refund guaranty policy, the best is to try.
