UEXO account terminated after profitable gold trading

I deposited USD 50 and made a profit trading gold around a news event. Instead of receiving a normal withdrawal, my account was terminated, my profit was removed, and I was only offered my original deposit back.

The explanation referred to abusive activity, but I was not given evidence showing what rule I broke. I need a proper review with the trade records, the applicable rule, and a written basis for removing the profit.
