On November 28th, the exchange experienced an outage, and brokers directly encountered slippage that expanded infinitely, resulting in margin calls across multiple investor accounts, including mine. Although I use EA trading, every order placed by my EA has notes and comments. However, after the outage, the spreads widened indefinitely, creating an extremely poor trading environment. Brokers have the responsibility and obligation to maintain the stability of their systems, but after the outage, the exchange failed to do so. Additionally, none of the orders placed by the EA had notes, and the platform system engaged in malicious operations. I checked every order—those without notes require a reasonable explanation from the broker, which they were unable to provide.
