You seem to be keen to make this a personal matter, if not also a racially based matter.
However, this is a forum for traders and for people who want to be traders. Being a trader demands many qualities, and evidence-based unemotional decision-making are high amongst these. Traders are not sheep who can be led around, and they are not children who can be pushed around. We've all been round the block too many times to simply accept what someone says, simply because they said it. Do you think we are that simple?
Its not good to hear that you lost money. But the facts are that firstly, YOU lost the money. A mature ambition now might be to take responsibility and grow from the experience.
Secondly, you came here AFTER you had lost the money. I only wish we had seen you posting questions on technical analysis and trading strategies and risk management before you jumped into trading with both feet. Questions from new traders are the life-blood of a forum like this.
Thirdly, your intentions on coming here were to cause reputational damage to a legitimate business through the use of vague unsubstantiated accusations. You have so far shown no interest in finding any trading techniques which you could use to make good your losses.
Stop ranting about this firm. What are you actually going to DO?
