Revoke traders' profitable orders without permission

XAU/USD slumped by $115 on the evening of October 9. The trader opened sell with stop limit. Each order was sold at the stop limit price. And we can trade normally at that night in SAFUMAX. While SAFUMAX revoked all the orders on the grounds of abnormal trade the nest afternoon, resulting that traders' accounts became negative. How can we trust such platform which shinks responsibility? We can't make money.
