As for providers I am sure you are more of the expert since your experience far exceeds my own with Zulu trade. If I was a follower I would find those traders who are profitable yet enters a pair with a stop already in place instead of the defaulted 500 pips. If multiple entries are on the same pair, what is the trader's main objective. I would be careful to look at the cross pairs traded because this can easily be hidden in which a martingale approach still exists. Its in the US providers best interest to not commission hunt because of Zulus formula included with an initial balance attached to every Zulu trader. This protects many of the followers from extremely large drawdowns. For example the #1 trader fibotradingchris would generate a mere 3033 month commissions if he lived in the US but obviously he lives elsewhere so he commission hunts currently in a ridiculous 23 trades with a drawdown of 652 pips. Zulu guard is an option to protect capital but would you place your hard earned capital in his trust. Well its entirely up to you.
I am hoping Zulu will protect the followers and to filter from the lowest initial balance if they are already placing these restrictions on all US signal providers. This is just my own thoughts and opinions and if you are following someone we should keep our eye on, please let me know and I will again conduct my own analysis.
