Doris 9, I'll take this in English but I guess you mean Coretta Lavern Andersson?
I know some people who have traded with her. She is not an embezzler, as Hotforex allows for an investors account, and a traders account. You keep the former, and only you can transfer money, and change passwords on all accounts. So the trader (Coretta), can only trade. Your money is in that way protected in the same way they are in traditional asset managing companies.
As you correctly point out, she takes slightly more than 30% of monthly gains as commission. That's monthly gains.
To illustrate what this could mean to you as an investor. Let's assume you invest one million.
Scenario A: She takes your 1 000 000, takes on positions, at the end she exits with 3 000 000. She takes one third in commission, you get 2 000 000 = 1 000 000 in profit (which you have to tax, if you're obedient).
Scenario B: Same as above, but at the end all the positions were losses, and you only have 20 000 left. Your loss = 980 000, her loss = 0.
Now, imagine instead scenario C: Here we have a longer time frame, you don't order her to exit and she takes on multiple trades and exits them according to the patterns above A B A B (lets call them A1 B1 A2 B2), stop, and then you stop trading with her. Thus she trades to 3 million, looses almost everything to 20 000 (and by an intended-for-us pedagogic miracle) trades up to 3 million again, and then tragically loses almost everything. How much profit do you and Coretta make?
A1 -> Coretta earns 1 million in commission (you don't withdraw so you earn nothing yet)
B1 -> nobody earns
A2 -> Coretta earns 1 million again
B2 -> Coretta loses nothing, but your loss = - 980 000
In total:
Coretta earned 2 million
You lost 980 000
Who pays commission? YOU! So you end up paying here 2 million which means that you lost 2 980 000!
Or, the pendulum swings to and fro the amount you started with: one million to 20 000 to 900 000 to 20 000 to 890 000... each time you are hoping to recover your initial sum invested, each up-turn you have to pay her commission, and in the end you may lose it all.
Hopefully you are not an idiot and you understand why such a deal is bad for you. So if you are going to trade, you have to renegotiate the terms of the contract.
Customary in hedge funds is a slight yearly commission (say 2%), and then 20-25% of all gains when you withdraw money. So not monthly, like in corettas case, nor do you pay when the trader gets back to zero after squandering parts of your money. Remember, traders and asset managers get paid to earn and protect your money, not to recap money after they themselves have lost it.
Now another point is Floating P/L. Or in other words, the amount of your capital dedicated to positions. She mentioned--and I have confirmed with others--that it should be max 10%, sometimes 15% in exceptional circumstances.
What happens? Wham! 50% or more. So almost all of your capital is in positions in the negative, that if you close, you lose. Feeling hijacked?
If you are going to let her trade, do your due diligence. Don't believe her words, but let her show the goods. Where are those that can show a five-year account with her trading it, going consistently plus, never hitting below the initial investment (for reasons explained above)? Ask her to put you in touch with these people, and ask them to show them their Hotforex accounts so that you can verify what has really gone on. It's relatively easy to be doing well for one year, just out of random chance, but it's the ability to go through financial crisis, a weird Trump election and so on, without your money taking a hit.
And her credentials... Do your due diligence. Where's her CV? Who can corroborate that she worked at this place or that? Remember, this is business and not your friend. Trust doesn't have a place here. It has to be proven, not assumed just because somebody is friendly.
And the obvious: If she is such a good trader, where are her riches? She should be enormously wealthy, no?
Think! Be critical! Sort out the dross from the gold if you are gonna invest your money. This may feel like your ticket out of poverty or unfortunate financial situation, but feeling of urgency is precisely why mediocre investors lose their money, and fall for all kinds of scams.
So go ahead if you want, Doris, but know that this is a high risk investment, and that you should get an education in investing your money overall, how you actually grow your capital in the safest way over 20-30 years. Or just go to the casino.
