Too late for a Traders Court case. FxSystems and every broker associated with it is now marked as a Scam in the reviews. AsstModerator promises a formal Scam Finding is on the way.
If you have't filed with eConsumer.gov, please do so. Try to include details like exactly what accounts you sent money too, IP addresses on any emails you got from them etc.
Also, check and see if your country has a central place for reporting online financial fraud. If you can find it, please share the link.
Regarding what Stevesmain said about eConsumer.gov:
Don't hold your breath on them getting involved!
earlier in the year one of them informed that it is their policy not to respond.
I think you misinterpreted how eConsumer.gov works.
They don't ever "get involved" in cases or respond. That's not their job. Their mission is to act as a central place where victims of online financial fraud in ALL countries can file reports. Police and regulators in member countries can request copies of everything about a specific scam from eConsumer.
So, imagine if you are a cop or an agent at a regulator and you are investigating FxSystems because some people complained. With one message to eConsumer, you can get a wealth of additional information submitted by consumer victims from around the world. If you are lucky, some of those files will include critical information that you don't have, but desperately need. Maybe all your victims deposited by some online method, but some of those eConsumer reports show the bank accounts used to receive bank wire deposits.
Every detailed report submitted to eConsumer may be the one which provides a police officer or regulator with some critical piece of data needed to find, prosecute, and/or recover money from scammers.
