If this is Managed account, why your Open trades and history are private? How I can invest in something i can not see trades? This could be risky or martigale, because it is private or something stolen.
For me, I understood well why the Trader make the history as Private.
As my experience, they're many cheated peoples outthere use the good performance record here for their promotion pusposes in their website (please googling, and you'll find it). It's easy to use the one of good performance trader link (like this kondakov link), and put this link to be their performance, and they accrued as their performance to confince the customers.
So, the trader just try to avoid such cheat thing by make the history as Private.
BTW, what Kondakov offer is Managed Account, so as the investor you just need proven good track record from third party publisher like this myfxbook.com. More longer the performance and make profit consistently in long run, it'll more better.
So, why do you need the detail of history?
If you try to look in detail regarding the history of the trades, it could be you're trying to 'learn' how is the trader doing the trades, so the forum is not here, but in the 'learning forum' instead of 'managed account forum'.
