My account is closed for no reason and no trading profit will be withdrawn

I opened a trading account in Tri in October. I didn’t expect that my account suddenly failed to log in and was disabled when I was doing a transaction. Later, I received an email from them saying that my account violated the rules and they will only returned the principal. I want to ask which rule did I the violate. Their customer service just have one sentence which is this is the decision of their company without explanation. I upload my transaction record
