You can easily pass the challenges between 30 and 60 days! (depending on the market trend, it can be less or more) We do not have any guarantee to pass the challenges, if you have experience, the guarantee to pass the challenge is a wrong word ! If you lose your challenge for any reason,the license will not be counted among the used licenses and your licenses will be reset and you can start again. Also, the robot has the possibility to specify a forced exit %! for example, in the settings, you can set the maximum loss option to 3% or 4% so that your challenge is not lost in difficult and unpredictable conditions.
