Is anyone familiar with Duplikium (Trade Copier) and able to offer useful information on the service and the company?

Thanks.

Interested to get more feedback also. I tested their LMAX to MT5 (beta) copytrading, in order to dupplicate LMAX/SierraChart trading to social trading (Darwinex). After a bug report (wrong qty during partial closed) that was quickly fixed in the next hour, it seemed efficient, as well as very fast. They claim that the LMAX copytrading is the most performant, above MetaTrader: it seemed to show as instantaneous when demoing. I liked the options to filter instruments and select trades by an on/off switch, the ability to choose how you want your SL and TP copied, either as levels transmitted and respected or as market orders only when hit. Hedging was not supported, copying net positions only, which is better to save on unnecessary fees (double commissions & swaps). Mobile trading without a VPS, neither a platform running, for the purpose is supported, since the bridging happens online.
I really disliked that they’re cloud based, inviting you to enter on the client access all your logins and passwords (master and slave)... they claim that the info is crypted when asked (though no mention on the site itself), yet I wonder how secure that is. Also awkward, no legal mention of the company info (address, CEO, etc) displayed
I was surprised to see how many staff support they have, which could imply a juicy business

After more lenghty tests, I cannot recommend that bridge service between LMAX and MT4/MT5. Too many unresolved and unpredictable bugs of different kinds

@Kalisto,

Your security instinct here is dead on. Handing over live account credentials to a cloud service with no published security audit, no company legal info, and just a verbal "it's encrypted" -- that should make any trader uncomfortable. The fact that you caught that immediately says a lot about Duplikium's transparency gaps.

A few things worth thinking about in this Duplikium review:

• Credential exposure -- Any cloud copier that stores your broker login is a single point of failure. If they get breached, attackers have direct access to your funded accounts. At minimum you'd want to see 2FA, IP whitelisting, and API key scoping rather than full login credentials.
• No legal entity info -- This is a real red flag. Legitimate fintech companies display their registered address, jurisdiction, and leadership. Without that, you have zero recourse if something goes sideways.
• The bug pattern -- Quick fix on the partial close issue is encouraging for support responsiveness. But the real question is how many edge cases surface once you're running live size across multiple instruments. That's where Duplikium's trade copier -- and most copiers honestly -- tend to break down.

For anyone researching Duplikium reviews or evaluating trade copiers in general, here's a baseline checklist: run at least a week on micro contracts or paper to measure actual slippage, test during a contract roll week (that's where things get ugly), confirm your specific broker's order types are natively supported, and always check if there's an API-key-only option instead of full credential sharing.

Since you're on SierraChart trading ES, CL, and the rest -- worth looking at whether your broker offers native allocation or copy functionality. Sometimes the simplest path skips the third-party risk entirely.

Good detailed Duplikium review. This kind of honest feedback is exactly what the community needs more of.
