Hi Markus,
The robots are created using blackbull historical data. However, you don’t need to just use the blackbull broker as you can also use other brokers / prop firms. Recently one of our traders picked the top 5 robots, placed them on an Infinity Forex Fund challenge, and got funded within a few months.
I, on the other hand, use a different approach. When I use robots with a different broker / prop firm I forward test them with a small lot size like 0.01 for a week or two. I then select the best performing robot to trade with a normal lot size.
As to the magic numbers not being the same. When the robots are updated with EA Studio they will automatically be given a new magic number.
Alan,
