I have indeed an account on Zulutrade, admittedly it's out of curiosity only and not active at the moment, as I've found no signal provider with a trustworthy equity curve yet.
According to Zulutrade, there are only about 55 followers who have NOT lost money. Those lucky 55 are listed on their Top Followers list that you can check out here: https://www.zulutrade.com/performance (click on "Followers"). Their profits range from 800% at the top of the list, to 0% at the end at rank 55. So we can assume that all followers below rank 55 have either lost money, or are not long enough at Zulutrade to appear on their list.
When you consider that Zulutrade has about 85000 followers - at least that's the number of users on their forum - we can calculate a probability of 55/85000 = 0.07% of NOT losing money in the long run with Zulutrade.
I congratulate you that you have not lost money in December, but am afraid that this won't give you more hope than all the other followers. All of them win a year or so. That is perfectly normal and just the characteristic of grid trading or similar high risk / high win rate systems. If you still have your money after 2 or 3 years, it's an entirely different matter - then you'll indeed belong to the lucky 55 who survived Zulutrade for some longer time.
Funny probability math - sorry mate that i'm laughing at it, well you need to get more active with zulutrade and actually get to know the platform right, otherwise you would know that not every followers or traders account goes public - there is an option you choose to get copies and/or not.
i am counting my friend, one full year has passed, and getting now into my second one. Obviously, to stay means i am winning :clover:
good luck to find your provider, but looking from the way you writing maybe you should think about getting out of forex, and maybe smth more stable : like mini stocks or even bonds
