If you suspect that your Forex broker is cheating you in the Forex trading business, the first thing you should do is to document the situation. Look for patterns in their activities and make notes of any suspicious behavior. Be sure to include dates and times of activities, as well as any other relevant information.
Next, contact the broker and ask for an explanation of the activities you have observed. If you don't get a satisfactory answer, it's time to take legal action.
You should contact a securities lawyer that specializes in Forex trading. The lawyer will review your documentation and advise you on the best course of action. Depending on the type of fraud, you may need to file a complaint with the Financial Industry Regulatory Authority (FINRA) or the Commodity Futures Trading Commission (CFTC).
You should also contact the Securities and Exchange Commission (SEC) and file a Form 8-K. This form is used to report any material changes that affect your investments. It is important to document the situation and report the fraud to the proper authorities.
Finally, you should consider joining a class-action lawsuit. If your broker is found guilty of fraud or other illegal activities, you may be able to recoup your losses.
