Hi Stephen
Welcome to the forum
I think from my experience so far that Crescendo is a viable robot.
I like the robots that have a logic that you can understand instead of black boxes.
I am also using Megadroid that so far has produced profitable months.
And I am also using cash compounder that is a martingale style robot that even if it can make you profits when there is a trend,
in a ranging market can cost you a lot when it runs out of money.
The idea of this forum is not to base ourselves on robots but do our own analysis and trade it.
Robots could (and should) be used with small risk percentage first to pay for the creators of the robots and then add a small amount every month to our capital.
